[sr-dev] kamailio 4.1 segfault with MySQL auth

[Peter Villeneuve]

Well I ended up dumping the core and this is what GDB tells me.
How can tcp_main.c be missing if I installed the deb packages? Weird.

What do people suggest I do from here? Remove the deb packages and compile
directly from git?

Thanks,

Peter
