Problems with Data Types, High Severity (2)

aiAnim.h
[+] class aiAnimation (1)

	Change	Effect
1	Size of this class has been changed from 1052 bytes to 1060 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.
