Summary: [patch] Segfault - Perhaps in sig_analog.c
Description:
Asterisk is segfaulting when an incoming call from a PRI span is being sent
(dial) on to analog group.
I will attach a backtrace. This has happened three times and I was able
to catch it the last time.

Unfortunately, it is not advancing the channel at all when trying to
allocate with this patch. Here is what is happening with that patch
applied. You will see the first call comes in and is allocated properly.
The second call comes in and it is sent to channel 120 which is currently
in use. I hang up and try again and it continues to try and send the call
to channel 120.

Without the patch, you will see that the first call comes in. The second
call is then sent to channel 120 which is in use. I hung up and tried
again. This time the call was sent to 119. But upon hanging up, asterisk
segfaulted. I believe that I hung up the first call and then the second.
I don't remember too well now.
