Problems with Symbols, High Severity (16)

	Change	Effect
1	Parameter f_rng of type int()(void,unsigned char*,size_t) has been added to the calling stack at the middle position.	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.
2	Parameter p_rng of type void* has been added to the calling stack at the middle position.	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.

Problems with Data Types, Medium Severity (3)

	Change	Effect
1	Field Vf has been added at the middle position of this structural type.	1) Size of the inclusive type has been changed. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.
2	Field Vi has been added at the middle position of this structural type.	1) Size of the inclusive type has been changed. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.

	Change	Effect
1	Size of field rsa has been changed from 148 bytes to 172 bytes.	1) Size of the inclusive type has been changed. 2) Previous accesses of applications and library functions to this field and fields at higher positions of the structure definition may be broken.

Problems with Data Types, Low Severity (3)

	Change	Effect
1	Size of this type has been changed from 148 bytes to 172 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Base type has been changed from int()(void,int,size_t,unsigned char const,unsigned char,size_t) to int()(void,int()(void,unsigned char,size_t),void,int,size_t,unsigned char const,unsigned char,size_t).	Replacement of the base data type may indicate a change in its semantic meaning.

	Change	Effect
1	Size of this type has been changed from 460 bytes to 484 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
