Please copy the output of:

grep "Pointer Size" stage1_core.ptx

Thanks for the help, it was:

//  Target:ptx, ISA:sm_10, Endian:little, Pointer Size:32

I've added "-m 64" to the NVCCFLAGS, and now it looks better:

//  Target:ptx, ISA:sm_10, Endian:little, Pointer Size:64

Unfortunately, after a recompile, mprime now just segfaults. :(
