The query described in

Also on ARM?
yes, this is ARM (aarch64).
That other report said that memory is leaking and implies (?) the OOM
killer, but you're talking about a segmentation fault, so it seems
like a different symptom (even if the root cause is same), right?
when jit is disabled, the query runs ok in < 2 seconds.
when the issue happens, it takes > 30 seconds and then results in a 6GB core.
That situation is clearly reproducible, so we can help troubleshooting in
case you want to look into details.
Can you get a core file, and gdb backtrace?
find a core here:
https://my.hidrive.com/share/bz2zb2alkp do you have instructions for the gdb backtrace?
