Problems with Data Types, High Severity (1)

	Change	Effect
1	Size of this class has been changed from 36 to 8 bytes.	1) The class has only inline or auto-generated constructors which will be copied to applications at compile time and will allocate an older memory layout. Call of any exported method of this class may access a memory outside the allocated objects or inside the older memory structure and result in crash or incorrect behavior of applications. 2) The memory layout and size of subclasses will be changed.

Problems with Data Types, Medium Severity (2)

	Change	Effect
1	Field total 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 values 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.

Problems with Data Types, Low Severity (2)

	Change	Effect
1	Type of field slot has been changed from valueno to Internal::RefCntPtr<ValueCountMatchSpy::Internal>.	Replacement of the field data type may indicate a change in the semantic meaning of the field.
2	Field slot has been renamed to internal.	Renaming of a field in a structural data type may indicate a change in the semantic meaning of the field.
