Problems with Data Types, High Severity (1)

regex.h
[+] struct regaparams_t (1)

	Change	Effect
1	Size of this type has been changed from 16 bytes to 32 bytes.	Layout of parameter's stack of several functions has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.

Problems with Data Types, Low Severity (8)

regex.h
[+] struct regamatch_t (4)

	Change	Effect
1	Field num_del has been added to this type.	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 num_ins has been added to this type.	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.
3	Field num_subst has been added to this type.	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.
4	Size of this type has been changed from 12 bytes to 24 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
