Description:Hello Everyone

I've recently come back to testing asterisk 1.6 and I've stopped short once again.

In this simple case I have two snom phones setup with sip accounts in a mssql db.I start the asterisk server, and can sometimes reregister the snom 320 so that it appears under sip show peers, but hitting reregister (on the phone) a few times, or having a snom 190 reboot, thus unregister and reregister causes a segmentation fault.

I have both a username field and a defaultuser field in the table (to try and get around the warning), but that still shouldn't cause a segfault.

I will upload debug and cli output momentarily

I had similar issue with

All the best

I should probably also mention that installing 1.4.17 with same configs works without issue.

Please follow the instructions in doc/valgrind.txt.

Hello Corydon

The system did not crash when running valgrind but I have uploaded the logs anyway. There are invalid reads there in the log so hopefully that will help.

I retested without valgrind and it seg faulted straight away.

Let me know if you need anything else.

This needs to be reported to the FreeTDS project.  Use the same valgrind output.  This is a double-free error within their own software.

Hello Corydon

Thank you for your help. I had been running freetds 0.64 (lastest from yum on centos 5.2)

I have since retested with 0.84 built from source and the crash does not occur. I get a mass of sip debugs but that is another story.

It is still strange that is does not crash under 1.4.17 but at least I now have something I can move forward with.

Once again thank you for your help.

Resolved with FreeTDS upgrade
