I encountered a single occurrence of this while building core-updates
(2073b55e6b964cb8ca15e8c74cb32dac00f05f0d). I couldn't reproduce the
hang a 2nd time, but in case it'd occur to someone else, I'm reporting
the problem here.

The build appears to be hung, peeking a single CPU core with no output.

The last output printed is:

The 'bench' program is the one responsible for such a long execution/hang.

The build of fftw had been ongoing for about 500 CPU minutes. It may be
related to the tests using more than one thread (some deadlock perhaps).

I've encountered the same here (*) -- I do not have access to the latest
output (only in /var/log/..., but apparently due to the buffering for
the compression, the 'Executing ...' is not available yet'), but the
same command appears in 'htop'.
(*) nthreads=2, running time=4 hours and 55 minutes and counting,
available CPUs = 16 as counted by /sys/devices/system/cpu.

(^) maybe the ik7e00x27o11v28 is responsible somehow? TBI ...
