Problems with Data Types, High Severity (2)

	Change	Effect
1	Size of this class has been increased from 2 to 8 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 costructor will break the memory of neighbouring objects on the stack or heap. 2) The memory layout and size of subclasses will be changed.
