Description:Have not used this codec in a while so not sure when the issue was introduced.  If  I have the codec_g729a.so in the modules directory when I start asterisk, it immediately crashes when loading it.  (I tried multiple flavors of codec_g729a-1.6.0_3.0.1)  It also crashes if I manually try to load it from the CLI.  Not sure if it is related, but transcoding from ilbc to g722 on the same system is problematic.  Backtraces are below:

Are you running on Asterisk 1.6.0.5 or 1.6.1 r174221?  I have tested both a recent 1.6.1 checkout and 1.6.0.5 with the latest codec g729 (opteron) w/o crash and calls being completed normally.  What CPU and distro are you experiencing the crash on?

It is 1.6.1 r174221 (checked out and compiled this morning)

Running CentOS 5.2 with the following Kernel
Linux asterisk 2.6.18-92.1.10.el5 #1 SMP Tue Aug 5 07:41:53 EDT 2008 i686 i686 i386 GNU/Linux

Edit:  I can give access to the server if needed.

I have recreated this on Centos 5.2 x86 under vmware.  Hopefully I can track this down, now.
By: Terry Wilson (twilson) 2009-02-10 13:07:14.000-0600

There is an API change between 1.6.0 and 1.6.1, so there is no version of codec_g729 for 1.6.1 yet, so we'll have to make one (shortly).  Stay tuned...
By: Terry Wilson (twilson) 2009-02-10 13:39:04.000-0600

Just as a follow up, the 1.6.1 version of the codec is now posted at downloads.digium.com
