Segmentation fault It sounds like you ran into the same problem that I did, which magnum has since reported as fixed. My guess is that maybe the fix was only applied for 64-bit make targets. magnum? Meanwhile, you may run the actual CUDA and OpenCL tests directly. The command: ./john | egrep 'cuda|opencl' will tell you the names of "formats" that use CUDA or OpenCL. Then you may test those with: ./john --test --format=phpass-cuda and so on. Thanks, Alexander
