Hello,
please, I'm trying to obtain a pythonic backtrace via gdb to be able to
debug deadlock situations in a multi-threaded program by attaching to
the running process.
I'm running the program under python2.4-dbg, When I try to load the
..gdbinit script obtained at http://wiki.python.org/moin/DebuggingWithGdb
, gdb crashes however with the following error (full session listing):
(gdb) attach 10753
Attaching to program: /usr/bin/python, process 10753
warning: no loadable sections found in added symbol-file system-supplied
DSO at 0x7fff575fd000

I've also tried to use the backtrace script here
http://mashebali.com/?Python_GDB_macros:The_Macros:Backtrace
But I get a different error:
(gdb) pbt
Invalid type combination in ordering comparison.
I'm using GDB version 6.6.90.
Could you please suggest what can I do to be able to get the backtrace?
Thank you,
Hynek Hanke
