Problems with Data Types, High Severity (6)

	Change	Effect
1	Size of this class has been increased from 36 bytes to 48 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.

Offset	Virtual Table (Old) - 6 entries	Virtual Table (New) - 6 entries

20	__cxa_pure_virtual	__cxa_pure_virtual

	Change	Effect
1	Size of this class has been changed from 12 bytes to 20 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, Low Severity (1)

	Change	Effect
1	Field parameters_ 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.
