Package: freeorion
Version: 0.5+git20230820-4+b3

Dear Maintainer,

I have done some extra search.

# apt install coredumpctl
# ulimit -c unlimited
$ freeorion

I have the segfault

$ coredumpctl list

       Message: Process 19100 (freeoriond) of user 1000 terminated abnormally without generating a coredump.


If I try to use gdb with this I get:

Coredump entry has no core attached (neither internally in the journal nor
externally on disk).


I have try to get some info, but the coredump was never generated. I also 
slow down freeorion and used gdb, but the segfault process go to zombi
state immediatly and I cannot get any info.


I see that also on Ubuntu there is the same bug open:
https://bugs.launchpad.net/ubuntu/+source/freeorion/+bug/2065925


I have found, with lsof, that the log files are not in .config/freeorion/
directory, but they are in .local/share/freeorion/freeorion.log and the
log don't have any more info than my previous report.



I have fount that if I download the 3.11.9-1 package from shapshost
https://snapshot.debian.org/archive/debian/20240410T203634Z/pool/main/p/python3.11/libpython3.11t64_3.11.9-1_amd64.deb

and replace the libpython3.12.so.1.0 library with the libpython3.11.so.1.0 
one the game work correctly


I have also try to set logs to debug and than trace for the freeorion server
but I don't have any more interesting info.
With debug option for freeoriond there are few line that are present also
with 3.11 python library. With strace it generate big log files, but I
haven't see anything.

Ciao
Davide
