Description:See-ing messages to (I thought that was fixed with the patch from OEJ to chan_sip??

When I did a few reloads I see the following at the CLI:
   -- Setting default indication country to 'nl'
   -- Reloading module 'res_adsi.so' (ADSI Resource)
 == Parsing '/etc/asterisk/adsi.conf': Found
*CLI> Feb  2 18:06:58 WARNING[6151]: chan_sip.c:448 __sip_xmit: sip_xmit of 0x8117dcc (len 530) to returned -1: Invalid argument
Feb  2 18:06:59 WARNING[6151]: chan_sip.c:448 __sip_xmit: sip_xmit of 0x8118004 (len 591) to returned -1: Invalid argument
Ouch ... error while writing audio data: : Broken pipe
Segmentation fault

I reproduced this twice. The messages to did not appear but only after the reload. I tried to reproduce this a third time, but then I came into a deadlock. The fourth time also a deadlock.

The problems started after the latest cvs update (maybe the messages patch from oej & ww?)

I have a backtrace attached (debug_info.txt).

fixed in cvs... I have tested it on my system it no longer crashes.

I get still crashes. Will attach backtrace and CLI output.
