Description:	This has only happened once so far, but I did a sip show peer <PEER> and got a core dump today.  gdb shows in ast_cli.c:646.   ****** ADDITIONAL INFORMATION ****** This happened after I did a sip show peer just after a reload where I changed an allow= field in sip settings (uncommented an allow=g729).  On a side note, I no longer seem to be able to make g729a to ulaw calls (hence the changes I was trying to make to track down the problem--i will probably be opening a separate bug for this).  I am running  CVS-HEAD-06/23/04-01:07:37

By: jrollyson (jrollyson) 2004-06-23 14:44:11 Hmm... I don't call a crash a feature... Can anyone confirm this or provide any additional info? Also, can we get some background info? OS, kernel version, basic HW specs? By: Mark Spencer (markster) 2004-06-23 14:49:44 Runs clean under valgrind here.  The stack trace doesn't look very helpful here, might help to poke at the core file. By: Terry Wilson (twilson) 2004-06-23 14:50:55 yeah, forgot to mark the severity.  Sorry about that.  Dell PowerEdge 2650 2GB ram dual Xeon, CentOS  linux kernel 2.4.22-1.2174.nptlsmp. By: Mark Spencer (markster) 2004-06-23 15:27:50 This had to do with unloading and reloading the codec_g729a.so module.  The bug that caused this crash was in codec_g729a.so and has been fixed with new modules on the FTP site for all glibc 2_3_3 architectures except x86_64 which should get built tonight.
