re: Exception 13: General protection fault at o1A7...

A GPF fault means that a) you are trying to write intro memory that is designated as read-only, b) are attempting to execute data bytes as thiugh they were instructions, c) trying to access instructions as thought they were data.

All of these are triggered by bad pointer addresses. Check the validity of the addresses in all of your pointers. Use asserts.
