Problems with Data Types, High Severity (3)

	Change	Effect
1	Virtual method WPXPropertyListVector::append ( WPXPropertyList const& elem ) has been removed from this class.	The layout of v-table has been changed. Call of this virtual method or any virtual method at higher position in this class or its subclasses may result in crash or incorrect behavior of applications.
2	Virtual method WPXPropertyListVector::count ( ) const has been removed from this class.	The layout of v-table has been changed. Call of this virtual method or any virtual method at higher position in this class or its subclasses may result in crash or incorrect behavior of applications.

	Change	Effect
1	Size of this class has been changed from 8 bytes to 4 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.
