PM1 stalls just before completion

[ghost]

Please see attached log files.
Both run on Vega 56 (two different cards) and i5-3550 (two different CPUs) with amdgpu-pro 19.20 on Ubuntu 18.04 with recent or latest GpuOwl.
PM1-143791129.log
PM1-143792009.log

P.S. -- running the same software and Vega 56 instead on Xeon X5675, the first P-1 run always completes but the second hangs at the end of Stage 1. My workaround in this case is to put only one entry at a time in worktodo.txt and restart GpuOwl from scratch for each exponent.

I've revamped a bit P-1 (fixed a few errors), please retry with a recent version and re-open if the issue is still present.

Hello Mihai, Thank you for looking into issue #62, and also thank you very much for writing GpuOwl!  As you may have noticed, I've been using it a lot. I've tried updating to a later version to see if it resolves issue #62. Unfortunately it doesn't; it makes it worse by removing the work-around I was using. No big problem: I'll continue to use the older version for P-1 for the near term. I won't be reopening this issue because it occurs on older hardware and I know you recommend ROCm. Eventually I'll upgrade...
