Problems with Data Types, High Severity (2)

	Change	Effect
1	Size of this class has been changed from 52 bytes to 48 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 Symbols, High Severity (3)

	Change	Effect
1	Type of return value has been changed from void to TiXmlString& (4 bytes).	Layout of parameter's stack has been shifted by 4 bytes because the return value became passed in memory as the hidden first parameter. All the parameters will be incorrectly initialized by applications.
