Hello Jan and Simon! I have two gnugk 2.3.2 (cvs) instances on two different servers at the same site and
they periodically crash with ‘Segmentation fault’. Gnugk is compiled with ptlib
2.8.0 and h323plus 1.22.0 (cvs 2010-03-24). I must
say that I had the same problem with 2.2.8. Below is the gdb
backtrace with some kind of warnings which I don’t
understand. I can also provide level 4 gk debug and
traffic dump recorded with wireshark. Just say what
info is needed for indepth diagnostics. Thanks! GNU gdb Fedora (6.8-37.el5) Copyright (C) 2008 Free Software Foundation, Inc. License GPLv3+: GNU GPL version 3 or later
