Problems with Data Types, Medium Severity (5)

	Change	Effect
1	Type of field overlap has been changed from fixed_t[2][32][18] (64 bytes) to fixed_t[2][32][18] * (4 bytes).	This field may be incorrectly initialized or accessed by applications.
2	The pointer level of field overlap 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.

	Change	Effect
1	Field skiplen 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	Type of field main_data has been changed from unsigned char[1935] (1935 bytes) to unsigned char[1935] * (4 bytes).	1) Size of the inclusive type has changed. 2) Previous accesses of applications and library functions to this field and fields at higher positions of the structure definition may be broken.
3	The pointer level of field main_data 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 (3)

	Change	Effect
1	Size of this type has been changed from 13860 bytes to 9256 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
2	Field samplefreq has been renamed to sfreq.	Renaming of a field in data type may indicate a change in the semantic meaning of the field.

	Change	Effect
1	Size of this type has been changed from 1988 bytes to 60 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
