Problems with Data Types, High Severity (1)

	Change	Effect
1	Field mode has been removed from the middle position of this structural type.	1) Previous accesses of applications to the removed field will be incorrect. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.

celt_header.h
[+] struct CELTHeader (1)

to the top

Problems with Symbols, High Severity (1)

	Change	Effect
1	2nd middle parameter rate has been removed from the calling stack.	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.

celt_header.h, libcelt.so.0.0.0
[+] celt_header_init ( struct CELTHeader* header, celt_int32_t rate, celt_int32_t nb_channels, CELTMode const* m ) (1)

to the top

Problems with Data Types, Medium Severity (2)

	Change	Effect
1	Field frame_size 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 overlap 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.

celt_header.h
[+] struct CELTHeader (2)

to the top

Problems with Symbols, Medium Severity (1)

	Change	Effect
1	3rd parameter nb_channels has been removed from the calling stack.	This parameter will be ignored by the function.

celt_header.h, libcelt.so.0.0.0
[+] celt_header_init ( struct CELTHeader* header, celt_int32_t rate, celt_int32_t nb_channels, CELTMode const* m ) (1)

to the top

Problems with Data Types, Low Severity (1)

	Change	Effect
1	Size of this type has been changed from 56 bytes to 60 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

celt_header.h
[+] struct CELTHeader (1)

to the top

Problems with Symbols, Low Severity (1)

	Change	Effect
1	Base type of 2nd parameter data has been changed from char to unsigned char.	Replacement of parameter base type may indicate a change in its semantic meaning.
