Re: Query crash with 15.5 on debian bookworm/armv8

Thanks, this indeed solved the crash.
Just to make sure this crash doesn't have anything to do with my
setup/config (I'd changed quite a few settings in postgresql.conf),
I gave it a try on a fresh bookworm install and it also crashed immeditaly.

I also gave Ubuntu 23.10 a try (15.4 built with llvm-15) and it worked
as expected, explain analyze even mentioned the JIT was active.

I've filed a debian bug report with a link to this discussion and a
plea to build postgresql against llvm >= 15:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1059476

To be honest I don't know why llvm-14 was chosen, as 15 is also
available in bookworm.

Thanks & best regards, Clemens
