The program crashes on a LES instruction (opcode 0xC4) which is an 
invalid instruction in 64bit mode. Why it crashes there is beyond me, 
but its really annoying!

If anyone better at debugging than I am wants to give it a try, it would 
be great, at least to pinpoint what is leading to the crash.

I am using Windows 7 x64 build 7100.
