compiling on visual studio 2012 express on 64 bits
I have tested both asm version and noasm version of ttmath with Microsoft Visual Studio 2012 and both versions work fine. If you still experience such a problem then show your code and compile options.
Hi Tomek, I've modified asm source to make it work. I simply renamed a few references of esp register to rsp (64 bits stack pointer). Maybe on your os the high 32 bits of rsp are all zeros so no crash for you :)
Thanks a lot for your library
