This probably isn't super-general, but it's a first stab at using kill -11 to generate a core file instead of gcore.

# we have found that gcore doesn't yield as useful a core file
# as that yielded by a signal-caused core dump. So we are going to change
# the strategy to sending a SEGV signal to the asterisk process,
# and have it 'burn to the ground', leaving behind a core file.
# the main difference is that you cannot control where the
# core file will end up. We will assume that safe_asterisk was
# used to start asterisk, and the core file should therefore end
# up in /tmp (because safe_asterisk cd's there before starting asterisk).
# if this is not the case, set DUMPDIR to the place where the core
# file can be found.
