Problems with Symbols, High Severity 13

	Change	Effect
1	Type of 11th parameter k has been changed from int (4 bytes) to double (8 bytes).	The parameter became passed in the register instead of the stack. This may result in crash or incorrect behavior of applications.

	Change	Effect
1	Type of 1st parameter param has been changed from int (4 bytes) to long (8 bytes).	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.

1	Type of 1st parameter param has been changed from int (4 bytes) to long (8 bytes).	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.

	Change	Effect
1	Type of 1st parameter p1 has been changed from int (4 bytes) to char (1 byte).	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.

	Change	Effect
1	The pointer level of 1st parameter param has been increased from 1 to 2.	The library function may try to access unallocated memory by the dereferencing of old parameter value and therefore cause a crash of applications.

	Change	Effect
1	The pointer level of 1st parameter param has been increased from 0 to 1.	The library function may try to access unallocated memory by the dereferencing of old parameter value and therefore cause a crash of applications.

	Change	Effect
1	Type of 1st parameter param has been changed from *intconst** (8 bytes) to long double (16 bytes).	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.

	Change	Effect
1	Type of return value has been changed from int (4 bytes) to struct SomeStruct (32 bytes).	1) The return value became passed in different register as the hidden first argument (address of the space on the stack provided by the caller) and therefore distribution of parameters on the available registers and stack will be changed. All the parameters will be incorrectly initialized by applications. 2) Applications will read the wrong memory block instead of the return value.

	Change	Effect
1	Size of this global data has been changed from 4 bytes to 2 bytes.	Applications will obtain a different value and execution may change.
2	Type of this global data has been changed from int (4 bytes) to short (2 bytes).	Applications will obtain a different value and execution may change.

	Change	Effect
1	Type of 1st parameter param has been changed from *intconst to long double (became non-const**).	This function may change parameter param, but it will be treated as const by old client applications. This may result in crash or incorrect behavior of applications.
2	The pointer level of 1st parameter param has been decreased from 1 to 0.	The library function will treat the parameter as the lower-dimension array and will not read all elements. This may change the behavior of applications. NOTE: if this is out-parameter then this change may cause a crash of applications.

	Change	Effect
1	Field added_member1 has been added to this type.	1) This field will not be initialized by old clients. 2) Size of the inclusive type has been changed. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.
2	Field added_member2 has been added to this type.	This field will not be initialized by old clients. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.

	Change	Effect
1	Type of field i has been changed from long long[5] to long long[15].	Replacement of the field data type may indicate a change in the semantic meaning of the field.
2	Type of field j has been changed from long to long long.	Replacement of the field data type may indicate a change in the semantic meaning of the field.

	Change	Effect
1	Reserved field reserved0 has been replaced by f0.	This field will not be initialized by old clients.
2	Reserved field reserved1 has been replaced by f1.	This field will not be initialized by old clients.

	Change	Effect
1	Name of member with value 1 has been changed from BRANCH1 to BRANCH_FIRST.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
2	Name of member with value 2 has been changed from BRANCH2 to BRANCH_SECOND.	Applications may execute a wrong branch of code in the library and therefore change the behavior.

	Change	Effect
1	Field b has been added to this type.	1) This field will not be initialized by old clients. 2) Size of the inclusive type has been changed. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.
2	Size of this type has been changed from 4 bytes to 8 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Size of this type has been changed from 8 bytes to 32 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
2	Field c has been added to this type.	This field will not be initialized by old clients. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.

	Change	Effect
1	Parameter param became non-volatile.	Old client applications will pass volatile object to the function that may be optimized by the compiler and cannot handle volatile objects.
2	Type of 1st parameter param has been changed from int const volatile* to int*.	Replacement of parameter data type may indicate a change in its semantic meaning.

	Change	Effect
1	Type of 2nd parameter has been changed from ... (va_list) to int.	This parameter may not be initialized by old clients.
2	1st parameter param has been renamed to param1.	Renaming of a parameter may indicate a change in its semantic meaning.

	Change	Effect
1	Type of 2nd parameter param2 has been changed from int to ... (va_list).	The semantic meaning of the parameter may change.
2	1st parameter param1 has been renamed to param.	Renaming of a parameter may indicate a change in its semantic meaning.

	Change	Effect
1	The pointer level of return value has been increased from 1 to 2.	Applications will treat the return value as the lower-dimension array and will not read all elements. This may change the behavior of applications.
2	Type of return value has been changed from long long* to long long**.	Replacement of return type may indicate a change in its semantic meaning.

	Change	Effect
1	Type of return value has been changed from char* to char volatile*.	Replacement of return type may indicate a change in its semantic meaning.
2	Return value became volatile.	Old client applications will get volatile object instead of non-volatile, but may be optimized by the compiler and cannot handle volatile objects.

	Change	Effect
1	Name of member with value 1 has been changed from BRANCH1 to BRANCH_FIRST.	Recompilation of a client program may be broken with the error message: 'BRANCH1' was not declared in this scope.
2	Name of member with value 2 has been changed from BRANCH2 to BRANCH_SECOND.	Recompilation of a client program may be broken with the error message: 'BRANCH2' was not declared in this scope.

	Change	Effect
1	Field added_member1 has been added to this type.	This field will not be initialized or used by old client applications.
2	Field added_member2 has been added to this type.	This field will not be initialized or used by old client applications.

	Change	Effect
1	Value of member MEMBER1 has been changed from 1 to 2.	No effect.
2	Value of member MEMBER2 has been changed from 2 to 1.	No effect.
