Description

I get the following panic when killing hanging postgresql processes from the postgres-HEAD (upcoming 14) test suit:

I had that crash twice already at the same event. Unfortunately the following output is from the previous panic, but it should be the same:

I still have the crash dump and will be willing to provide that.

How to reproduce:

Set up a postgresql buildfarm member, use this config:

https://www.eenfach.de/~olbohlen/build-farm.conf

Then run:

35 0,3,6,9,12,18,22 * * * ( cd /export/home/elmer/c12 && PATH=/usr/gnu/bin:$PATH ./run_branches.pl --run-all --verbose >/export/home/elmer/c12/cron.out 2>&1 )

It will hang on the regression tests for posgresql-HEAD, 32bit built

so, I got this again. This time updated outputs (note, c12 directory indicates -m32 build, c12x is 64bit build).
Also this time I include kernel stacktraces for all relevant processes.

Sorry for not seeing this earlier.

In your initial posting, register `rdi` has some STRANGE contents. This suggests to me that you may be seeing a use-after-free bug.

Have you reproduced this using a DEBUG kernel by any chance? DEBUG kernels turn on the full kmem debugging AND all of the ASSERTs fire. A dump from a DEBUG kernel would be most useful, I think.

No, unfortunately it's not a debug kernel. If I remember correctly Andy Fiddaman had more insights on this issue, we chatted about it.
Also I think Robert should know about this one.
