If you still have the old core, can you get the content of f in frame 1 from gdb?

frame 1
p *f

If you are going to test with the patch I suggested in previous email, can you set MEMDBG=1 in Makefile.defs, then compile and install? It will be easy to detect if there is a buffer overflow somewhere.

Cheers,
Daniel

Hello,

can you try with next patch?

- http://git.sip-router.org/cgi-bin/gitweb.cgi?p=sip-router;a=blobdiff;f=modules/dialog/dlg_hash.c;h=d346800a848b6ae0477530d0b875c8d2c528d7dc;hp=6f944e1fcc00b892a838fd19b4891c92c7637290;hb=082a6c43938cf8e3839d46fd070e391bd522d4ed;hpb=8d6a981543a044fddc3448c93dba9ed35afac0c0

It is on master, but there was no much testing to port it to branch 4.0 so far.

Cheers,
Daniel

I can reproduce it consistently.
I am doing serial forking into a non-existent host, when the caller gets impatient, it cancels the call and send another invite.
this happens after that.

Hello,

can you get the output for 'bt full'? Probably you have to install the debug symbols (kamailio-dbg package) for getting something useful.

Another question, can you reproduce it? Or it happens sporadically?

Cheers,
Daniel
