I recommend: testing against the latest cuda version (currently: 11.5) if the issue still occurs there, filing a bug

Thanks for response. Bug replicated in cuda-11.5. Bug report filed https://developer.nvidia.com/nvidia_bug/3419212 Sorry for poorly formatted text in bug report, but I don’t seem to be able to edit my original post.

Thanks for filing the bug, I will link it to the one I filed, and clean it up if needed.
