Problems with Data Types, High Severity (1)

	Change	Effect
1	Size of this class has been increased from 8 bytes to 12 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 neighboring objects on the stack or heap. 2) The memory layout and size of subclasses will be changed.

Problems with Data Types, Low Severity (1)

	Change	Effect
1	Field m_code has been added to this type.	Size of the inclusive type has been changed. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.

Other Changes in Data Types (1)

	Change	Effect
1	Virtual method PresageException::code ( ) const has been added to this class.	No effect. You can add virtual functions at end of leaf classes with exported constructors.
