Description:Realtime config dumps core after making sql query.  Also, the supplied makefile patch fails on hunk 2, had to enter it manually.

I have a ethereal trace if needed.

Ya know a little bit of information would be helpful such as a backtrace.

Also, please try this with a fresh checkout from CVS.  If you still have the issue, please provide a backtrace.

drumkilla, could you please point me to some instructions on how to do a backtrace.  I'm not a programmer... just trying to help out.
By: Brian Jones (bjones) 2004-12-10 08:59:53.000-0600

BTW, I just tried with a fresh checkout of CVS head (same version as reported) and it still segfaults.
By: Russell Bryant (russell) 2004-12-10 09:38:35.000-0600

Sure!  I do very much appreciate your help.

cd /usr/src/asterisk
make clean; make valgrind; make install

run asterisk with -g so you get a core dump... let it seg fault

gdb ./asterisk core.<pid>

<pid> is the process id of the instance of Asterisk that just died on you.

Once you are in gdb, type 'bt'.  The output from that command is what we are looking for.

If you have any problems with this, please contact me or one of the other bug marshalls on IRC (irc.freenode.net  #asterisk  #asterisk-bugs).

Thanks!
