Hackish-fixed the crash when you run a game through run->execute in release builds. Some code is corrupting ebp and not preserving it, so I made execute() do that instead. Put a nice fixme in there in case anyone is worried. :p 

Yes you read the nickname correctly.
Yes I did take the time to fix a problem in pcsx2.
No you are not dreaming, I was bored.
