Problems with Data Types, High Severity (1)

	Change	Effect
1	Field code_size 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.

[+] struct _OrcProgram (1)

Problems with Data Types, Medium Severity (7)

	Change	Effect
1	Field chunk 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 code 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	Size of field vars has been changed from 7680 bytes to 8064 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.

	Change	Effect
1	Size of field vars has been changed from 5120 bytes to 5376 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 relative position of field insns has been changed from 13 to 12.	1) Applications will access incorrect memory when attempting to access this field. 2) Size of the inclusive type has been changed.
3	The relative position of field vars has been changed from 2 to 13.	1) Applications will access incorrect memory when attempting to access this field. 2) Size of the inclusive type has been changed.

	Change	Effect
1	Type of field value has been changed from int (4 bytes) to union orc_union64 (8 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.

Problems with Symbols, Medium Severity (1)

	Change	Effect
1	Base type of 1st parameter compiler has been changed from struct _OrcCompiler (15464 bytes) to struct _OrcCode (48 bytes).	This parameter may be incorrectly initialized by applications.

Problems with Data Types, Low Severity (9)

	Change	Effect
1	Size of this type has been changed from 44 bytes to 48 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
2	Base type of field vars has been changed from struct _OrcVariable (80 bytes) to struct _OrcCodeVariable (16 bytes).	Possible access of applications to incorrect memory through the pointer.

	Change	Effect
1	Size of this type has been changed from 15464 bytes to 15852 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Field _unused3 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 11992 bytes to 17364 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
3	Field code has been renamed to _unused2.	Renaming of a field in data type may indicate a change in the semantic meaning of the field.

	Change	Effect
1	Field flush_cache has been added to this type.	This field will not be initialized by old clients. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.

	Change	Effect
1	Size of this type has been changed from 80 bytes to 84 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
2	Field is_float_param has been renamed to param_type.	Renaming of a field in data type may indicate a change in the semantic meaning of the field.
