Description:I can consistently core dump Asterisk by enabling qualify on a sip peer that's configured to use transport=tcp.  Setting"qualify=no" eliminates the crashes.

Running via 'safe_asterisk' result:

Any chance to see you sip.conf?  We are using 1.6.0.1 in our lab with transport=tcp and qualifiy=yes with no problems.

What are the endpoints these peers or qualifying?

Both are lines on the same Cisco 7965.

Nugget, which options in menuselect 'Compiler flags' do you have enabled?

I have reproduced this and will take a look at it.

Nugget: Could I get you to try checking out the 1.6.1 branch and testing that to see if it is fixed for you there?  I can recreate the issue in the 1.6.0 branch but not the 1.6.1 and would like to see if the same is true for you.
By: David McNett (nugget) 2008-12-11 11:32:03.000-0600

Sure, I'd be happy to.  I had experienced the same problem with 1.6.1-beta2 but haven't tried beta3 or anything from SVN.  Will do so and post results.
