Problems with Data Types, High Severity (9)

	Change	Effect
1	Size of this class has been increased from 24 bytes to 28 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.

	Change	Effect
1	Size of this class has been increased from 12 bytes to 16 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.

	Change	Effect
1	Size of this class has been changed from 8 bytes to 16 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 odb::details::shared_base has been added.	The memory layout in this class has been shifted by 8 bytes.
