As it looks like * don't goes down after the SIGSEGV, it may an module or
related to the H323 implementation you built for use with *.
Well, try running everything (asterisk, any h323 daemon if so) with
strace, so you can see what might be causing the SIGSEGV to the module or
whatever it is.
I get random SIGSEGVs on linux boxes mainly when physical memory or mobo
are not Okay... Perhaps when your module is loaded (or cleaned up) it may be
using a certain part of the memory which causes it to crash (it may be lured
to the same bad place of memory if it's need for memory allocation is way
big).
