omfg plz translate it to fasm and get rid of includes so i may check it out...

You know, I am really getting sick of seeing asmcoders fucking retarded and pointless posts. Seriously, if you would like to "check it out" just go to the fucking website at the top of the code, you dumbass.

windwakr, I have added the code tags.

Bicyclist, you are running the same executable that works in 32-bit or you are recompiling for 64-bit?

Bicyclist: use OllyDbg to step through the code until you get the line which doesn't execute.

windwakr: lol.

Yes, I recompiled for 64 bit.

Quote:

Don't do that then. You are not using 64-bit pointers which probably are making all the mess.

From the debug output you show looks like the code is 32-bit actually but if it is not then you must either recompile for 32-bit (or use the same executable you use under WinXP 32-bit) or do a major rewrite of your code to support 64-bit properly.

Maybe you can post us the executable for the ones without MASM-skills
Then those of use (me, bitRake & others) can test and post the results. It can be many things: unaligned stack, unaligned SSE memory-access etc.

Don't know which it is - http://fdbg.x86asm.net/ - maybe helps...

I have experienced problems with OllyDbg under WinXP x64, but as far as I can recall, the only thing needed was just to forward the firsts exceptions to the program. I haven't tested OllyDbg 2 there though, perhaps it works better? Give it a try: http://www.ollydbg.de/odbg200j.zip

PS: I've used OllyDbg under 64-bit but debugging 32-bit apps, otherwise it really has no chances to work
