I suspect this is a driver bug. I'll look into it.

For a while the OSX drivers were very good, all formats worked fine. Latest nvidia driver segfaults with many formats. I guess we should just wait for a driver update. The above is with nvidia driver version 10.6.42 310.42.05f01

Version 10.6.47 310.42.05f01 did not fix it. I wish I could revert to the Yosemite drivers :cry:

@magnumripper What's the status on this?

magnumripper commented 1 month ago

I think I still have that old macbook but I have no idea where to look for it, lol. My current macbook passes self-test with its secondary devices (CPU and Intel UHD Graphics 630) but not on the primary AMD Radeon Pro Vega 20 Compute Engine. It doesn't crash though, just fails to compile the OpenCL.

Build log: SC failed. No reason given.
Error building kernel ../run/opencl/DES_bs_kernel.cl. DEVICE_INFO=522
0: OpenCL CL_BUILD_PROGRAM_FAILURE (-11) error in opencl_common.c:1293 - clBuildProgram

Forcing JOHN_DES_KERNEL=bs_f or bs_h doesn't help. I think we can close this - macOS has notoriously bad drivers, worse than AMD at its worst.

Oh, and no way to obtain build log?

OK, closing.
