Hello!

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1063253

Can people here confirm that problem with their Pi and Debian 12?
3.11.2-1+b1
Python3 is completely broken on that machine.

Mine isn't a 3B+ so the following may be of no use ...

Are you running just the 64 bit kernel or the 64 bit userland too?
If it's the latter I don't recommend that with only 1GB of memory.

I'm only running full 64 bit Bookworm on Pi 4s and 5s, and there are no
Python issues on those.

However there is an inconsistency with the material in the bug report.
Stefano quotes a STUR insn but if I disassemble it I get LDP at that

This could reflect the libc-level differences, but gen_dealloc is part

Are you running just the 64 bit kernel or the 64 bit userland too?
If it's the latter I don't recommend that with only 1GB of memory.

All the packages are arm64.

I am aware that they need more RAM, but does that create such errors?

It doesn't, you've got some configuration problem that will probably
only be installed by a reinstall. If you are going down that route I'm suggesting that for machines which only have 1GB and function worse with
a 64 bit OS and programs, you reinstall a 32 bit OS.

Just a wild guess on my part, but in theory if the program in
question called malloc() and neglected to check whether the
result was NULL, lack of RAM could be a contributing factor to a
number of segmentation faults or similar. There might be a
scenario where it could end up in an illegal instruction fault.
