Summary:                    IAX crashing Asterisk
Description: 
After updated Asterisk from SVN-branch-1.4-r80601 to 1.4.14, my Asterisk in
Server A is crashing, apparently this issue occurred when the call that
outgoing across the IAX trunk in Server B is blind transfered in Server A
between two IAX softphone.

I reverted  the Server A to SVN-branch-1.4-r80601.

Russell if you assign the bug for you, your login in the server is still
active, else I can send debug file.

Asterisk-1.4.14
Zaptel-1.4.6
Libpri-1.4.2

Neither backtrace really makes any sense.  They both look like:

http://bugs.digium.com/view.php?id=0  0xb6cd64d2 in socket_process

/lib/libpthread.so.0

However, socket_process() never calls itself, nor is it ever the first
function in a thread as this backtrace shows.

Do you know if this backtrace was done on a version of Asterisk compiled
without optimizations?  i.e. the DONT_OPTIMIZE setting?
