Problems with Data Types, Medium Severity (7)

	Change	Effect
1	Field fragment_index 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.

	Change	Effect
1	Field file has been removed from this type.	1) Applications will access incorrect memory when attempting to access this field. 2) Size of the inclusive type has been changed.
2	Field fp has been removed from this type.	1) Applications will access incorrect memory when attempting to access this field. 2) Size of the inclusive type has been changed.

	Change	Effect
1	Field x has been removed from this type.	1) Applications will access incorrect memory when attempting to access this field. 2) Size of the inclusive type has been changed.
2	Field y has been removed from this type.	1) Applications will access incorrect memory when attempting to access this field. 2) Size of the inclusive type has been changed.

	Change	Effect
1	Size of field unnamed0 has been changed from 20 bytes to 12 bytes.	Previous accesses of applications and library functions to the fields at higher positions of the structure definition may be broken.
2	Size of field unnamed2 has been changed from 16 bytes to 8 bytes.	Previous accesses of applications and library functions to the fields at higher positions of the structure definition may be broken.

Problems with Symbols, Medium Severity (1)

	Change	Effect
1	Type of this global data has been changed from char const[18] (72 bytes) to char const[26] (104 bytes).	Applications will obtain a different value and execution may change.

Problems with Data Types, Low Severity (9)

	Change	Effect
1	Field e 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 72 bytes to 80 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 20 bytes to 12 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 16 bytes to 8 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
2	Field table has been renamed to bitnum.	Renaming of a field in data type may indicate a change in the semantic meaning of the field.
3	Field table_len has been renamed to numbits.	Renaming of a field in data type may indicate a change in the semantic meaning of the field.

	Change	Effect
1	Field const_type has been added to this type.	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 table has been added to this type.	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 unnamed3 has been removed from this union.	Applications may access incorrect memory when attempting to access this field.
