Problems with Data Types, Medium Severity (5)

	Change	Effect
1	Type of this type has been changed from union to struct.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Size of field builtin has been changed from 40 bytes to 44 bytes.	1) Size of the inclusive type has changed. 2) Previous accesses of applications and library functions to this field may be broken.

	Change	Effect
1	Size of field lock has been changed from 24 bytes to 28 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.

	Change	Effect
1	Size of field multi has been changed from 52 bytes to 56 bytes.	Previous accesses of applications and library functions to this field and fields at higher positions of the structure definition may be broken.

	Change	Effect
1	Value of member FCEF_ALL has been changed from 1 to 3.	Applications may execute a wrong branch of code in the library and therefore change the behavior.

Problems with Data Types, Low Severity (4)

	Change	Effect
1	Field trace_ref 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	Size of this type has been changed from 16 bytes to 20 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Size of this type has been changed from 52 bytes to 56 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Size of this type has been changed from 40 bytes to 44 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

Other Changes in Data Types (2)

	Change	Effect
1	The member DFB_NOALLOCATION with value -1994780668 has been added.	No effect.

	Change	Effect
