Problems with Data Types, High Severity (13)

	Change	Effect
1	Size of this class has been changed from 4 bytes to 12 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	Size of v-table in this class has been changed from 28 bytes to 32 bytes.	The layout of v-tables in its subclasses has been changed. Call of any virtual method in subclasses may result in crash or incorrect behavior of applications.
3	Virtual method DBException::appendPrefix ( std::stringstream& ss ) const has been added to this class.	The layout of v-table has been changed. Call of any virtual method at higher position in this class or its subclasses may result in crash or incorrect behavior of applications.
4	The relative position of virtual method DBException::toString ( ) const has been changed from 3 to 4.	The layout of v-table has been changed. Call of this virtual method may result in crash or incorrect behavior of applications.
