CentOS screen segfault in libgcc_s - Mellnik - 04.01.2014

When exiting screen in CentOS 6.5 64bit (CTRL+C) following is being printed in /var/log/messages

Код:

kernel: samp03svr[6597]: segfault at 5b16a0 ip 00000000005b16a0 sp 00000000f45d5ffc error 15 in libgcc_s-4.4.7-20120601.so.1[18e000+1d000]

glibc.i686, libstdc++.i686 and gcc is installed and samp03svr has executable rights.
sp and ip always changes it also was segfault error 14 once but ****** didn't help.

Edit: Installed plugins: sscanf.so streamer.so mysql_static.so (R34) irc.so dns.so

Try to debug it. Install "gdb" (the GNU debugger) and execute "gdb sampsvr" and "run". If it crashes, the debugger will show more informations. Post them here. And when it crashes, execute "bt", this will print the backtrace (also post it here).

Perhaps you should try CTRL + A, D instead of CTRL + C when exiting screen. The first key combination (CTRL + A, D) detaches from the current screen.

Did following:

Код:

gdb samp03svr
run

CTRL+C to exit samp window

Код:

signal SIGINT (to simulate CTRL+C)

Output of gdb:

Код:

(gdb) signal SIGINT
Continuing with signal SIGINT.

Just noticed that with crashdetect and without gdb following is beting output:

Seems to be related to the query in OnGameModeExit. I will test it further and with may also with R35 to provide more info.

Yeah I usually do that after starting the server but with CTRL+C I want to stop the server not just exit the screen.
