Summary:                    Asterisk crashes on local_ast_moh_start
(Segmentation Fault)
Description: 
Scenario: Asterisk(A) connect to Asterisk(B) through IAX2 trunk.
Using res_timing_dahdi as timing source.

Call comes from PSTN to Asterisk(A), with DID to a SIP extension that have
an follow me configured to a external route (using IAX2 trunk) that point
to another SIP extension on Asterisk(B).

In this scenario I have two segmentations faults on Asterisk(A), 1000
calls per day.
Today I changed the IAX2 trunk between Asterisk(A) and Asterisk(B) to a
SIP trunk and until now, I do not have an segmentation fault.

I am suspecting that the problem is with IAX2 trunk.

Here we use a dialplan based on FreePBX, and it's so big. Looking to the
source code and the problem, we know the problem is the unitialised string.
The problem apparently occur only with IAX2 trunks, because we changed this
trunk to a SIP trunk and the problem did not occur again. Where I can look
for initialization  of mclass parameter?
