Bug#1014617: libfcgi-perl: perl is segfaulting and I think it's CGI::Fast

If that system has systemd, then one way to gather cores might be to
use systemd-coredump. That way a backtrace (with limited symbols)
might already appear in the journal.
Or for nearer inspection 'coredumpctl list'
and 'coredumpctl gdb [crashed pid]'.

Otherwise [1] mentions two other (virtual package core-dump-handler
providing) packages corekeeper or minicoredumper that could be helpful.
