Prime95 - automatic benchmark locks up

[rmaeder]

every morning, mprime (p95v307b9.linux64) locks up. It runs at 100% (so only one thread is running, instead of 64),
and is not interruptible. Running it in the foreground, I see this:

[Worker #6 Feb 28 05:45] Worker stopped while running needed benchmarks.
[Main thread Feb 28 05:45] Timing 3456K FFT, 64 cores, 8 workers.  

Your choice: 5

Waiting for worker threads to stop.
Waiting for worker threads to stop.
Waiting for worker threads to stop.
...

it never stops, and does not react to ^C, only ^\
It looks like the benchmark it tries to perform locks up.
This is on Debian bullseye, AMD Ryzen Threadripper 3990X 64-Core

For now, add "AutoBench=0" to prime.txt.
