If you have gdb installed, try gdb /usr/sbin/asterisk (or whichever path is appropiate) name_of_core_file, and send back the results of

and that should allow the developers or other people to work out what the problem is.

As for the f00f bug, its unlikely that would be causing problems, the mention of f00f is there so that you can check to see if the machine is vulnerable. From memory, most os's now include work arounds for that bug.
