Problems with Data Types, High Severity (3)

	Change	Effect
1	Size of this class has been changed from 16 to 24 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.
2	Base class StringValueRangeProcessor has been added.	1) Size of the class has been changed from 16 to 24 bytes. 2) The memory layout in this class has been shifted by 12 bytes.
3	Base class ValueRangeProcessor has been removed.	1) Size of the class has been changed from 16 to 24 bytes. 2) The memory layout in this class has been shifted by 12 bytes.
