What version of CVS are you using?

I'll try to reproduce this later today, not at my test environment right now though

We need a backtrace, not a core file.

If you need help with the backtrace, a bug marshall on #asterisk will be able to help you.

Ok, I figured it out. Some time ago, I had applied the patch from bug 935 (chan_sip.patch), but there is a small problem with it:

#ifdef MYSQL_FRIENDS
       if (!p) {
               p = mysql_peer(peer, NULL);
               inet_aton(p->tempaddr, &p->addr.sin_addr);
       }
#endif

has to be changed to

#ifdef MYSQL_FRIENDS
       if (!p) {
               p = mysql_peer(peer, NULL);
               if (p) inet_aton(p->tempaddr, &p->addr.sin_addr);
       }
#endif

Thanks for suggesting to look at the backtrace.
