Can you paste the full backtrace?
Tell me how to do full backtrace please...
I am on bookworm (test version)
See https://wiki.debian.org/HowToGetABacktrace
I pasted whatever gdb printed. I cannot understand what other options to use in order to get more information from gdb on that.
The GDB output from Comment 2 can't possibly be complete because in order to get that backtrace, you had to type `bt` at some point, which isn't in the text. I would recommend asking for help in a Debian forum.
