Problems with Data Types, Medium Severity (2)

speex_bits.h
[+] struct SpeexBits (2)

	Change	Effect
1	Type of field bytes has been changed from char[1000] (1000 bytes) to char* (4 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.
2	The pointer level of field bytes has been increased from 0 to 1.	The library functions may try to access unallocated memory by the dereferencing of old field value and therefore cause a crash of applications.

Problems with Data Types, Low Severity (2)

speex_bits.h
[+] struct SpeexBits (2)

	Change	Effect
1	Field owner 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 1012 bytes to 20 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
