Problems with Data Types, High Severity (1)

	Change	Effect
1	Size of this class has been increased from 68 bytes to 84 bytes.	1) An object of this class can be allocated by the applications and old size will be hardcoded at the compile time. Call of any exported constructor will break the memory of neighbouring objects on the stack or heap. 2) The memory layout and size of subclasses will be changed.

Problems with Data Types, Medium Severity (2)

	Change	Effect
1	Size of field basicBlocks has been changed from 16 bytes to 24 bytes.	1) Size of the inclusive type has been changed. 2) Previous accesses of applications and library functions to the fields at higher positions of the structure definition may be broken.
2	Size of field containedLoops has been changed from 16 bytes to 24 bytes.	1) Size of the inclusive type has been changed. 2) 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 (4)

	Change	Effect
1	Base type of return value has been changed from BPatch_module (112 bytes) to BPatch_object (24 bytes).	Applications will obtain a different return value and execution may change.

	Change	Effect
1	Base type of return value has been changed from BPatch_module (112 bytes) to BPatch_object (24 bytes).	Applications will obtain a different return value and execution may change.

	Change	Effect
1	Base type of return value has been changed from Symtab (724 bytes) to Module (28 bytes).	Applications will obtain a different return value and execution may change.

Problems with Data Types, Low Severity (6)

	Change	Effect
1	Size of field incomingEdges has been changed from 16 bytes to 24 bytes.	Size of the inclusive type has been changed.
2	Size of field outgoingEdges has been changed from 16 bytes to 24 bytes.	Size of the inclusive type has been changed.

	Change	Effect
1	Size of this type has been changed from 68 bytes to 84 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 112 bytes to 128 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
2	Size of field backEdges has been changed from 16 bytes to 24 bytes.	Size of the inclusive type has been changed.
3	Type of field allBlocks has been changed from *BPatch_Set<BPatch_basicBlock,BPatch_basicBlock::compare>** (16 bytes) to BPatch_Set<BPatch_basicBlock,comparison<BPatch_basicBlock> > (24 bytes).	Size of the inclusive type has been changed.

BPatch_basicBlock.h

[+] class BPatch_basicBlockLoop (1)

BPatch_flowGraph.h
[+] class BPatch_flowGraph (3)

Problems with Constants (1)

	Change	Effect
1	The value of constant DYNINST_MAJOR has been changed from 7 to 8.	Applications will pass an old value of this constant as the parameter to the new-version library functions, that expect a new one. This may result in crash of incorrect behavior of applications.
