1	Type of return value has been changed from void to PositionIterator& (4 bytes).	Layout of parameter's stack has been shifted by 4 bytes because the return value became passed in memory as the hidden first argument, that was used to pass the return value. All the parameters will be incorrectly initialized by applications.

	Change	Effect
1	Type of field internal has been changed from Internal::RefCntPtr<StemImplementation> to Internal::intrusive_ptr<StemImplementation>.	Replacement of the field data type may indicate a change in the semantic meaning of the field.

	Change	Effect
1	Base class Internal::intrusive_base has been added.	Possible incorrect access of applications to the memory occupied by the base classes.
2	Base class Internal::RefCntBase has been removed.	Possible incorrect access of applications to the memory occupied by the base classes.

Offset	Virtual Table (Old) - 6 entries	Virtual Table (New) - 6 entries

	Change	Effect
1	Type of field internal has been changed from Internal::RefCntPtr<struct TermGenerator::Internal> to Internal::intrusive_ptr<struct TermGenerator::Internal>.	Replacement of the field data type may indicate a change in the semantic meaning of the field.
