CUDA 64-bit compilation

[wombatman]

I'm trying to compile MSieve on Win 7 Ultimate--it actually compiles successfully, but when I actually run it, I immediately get a c000001d exception. Debugging in VS2012 gives the error at this line:

[CODE]0000000000402B53 vmovaps xmmword ptr [rsp+0B40h],xmm6[/CODE]

MSieve was compiled with core-avx-i as the -march flag. Any suggestions on what may be causing the error?


Edit: Alright, it's not a CUDA problem. Even just building with "make all WIN=1" and setting the march flag to native, I get the same error.

Edit 2: Compiling with march as -corei7 allows the program to work as long as CUDA is not involved. With CUDA=1, I now get a c0000005 exception.

Still can't get around the C0000005 exception error.

I get this far when I run Msieve with CUDA enabled:
