[Asterisk-Dev] Seg Fault with chan_local

[Brancaleoni Matteo]

Hi.
I'm running * cvs 10/09/2003 .
I'm trying to do a sort of webcall app, where
I put a file in /var/spool/asterisk/outgoing/ to generate 
the call. 
I want to dial an operator, showing him a caller id
composed from the web page, and when the operator
answers, call the number that wants to be called.

Here's my 'sample.call'
Channel: Local/operator at webcall ; my operator
MaxRetries: 1
RetryTime: 60
WaitTime: 30
Context: webcall
Extension: 01234566 ; number to be called
Priority: 1
Callerid: WEBCALL <01234566>

and my webcall context:
[webcall]
include => outerworld
exten => operator,1,Dial(Local/33 at interni,10,m)
exten => operator,2,Hangup

[outerworld]
exten => _0XX.,1,Dial(Zap/g2/${EXTEN:1})
exten => _0XX.,2,Hangup

I use chan_local, since call spooling works by calling the
number and then connecting to an ext.
What I wanna do is to go to an exten, do some stuff (agi),
and if answered go on with my call.
So specifying Local/blah as channel does the trick.
my exten gets called, some agi is done (in [interni] context),
and an operator answers. now it's connected with Extension 0123456, 
prio 1 in the webcall context (matched thanks to [outerworld] context).
That sort of 'nested local' seems to work, but sometimes I get
a seg fault.
is that an error, or I'm doing that in a 'strange way' ;) ?

here's the bt:
