There's nothing between them. If they absolutely _must_ use SIGHUP
because, presumably, some third party program is sending it to their
debugging target, then they can put a interceptor process's PID in place
of the PID file of the debugging target that is being sought out. This
interceptor would catch the HUP and emit a SEGV to the real PID. The
perl/ruby and even C <signal.h> code for this is less than 10 lines.

If there is no third party program emitting SIGHUP, then it doesn't
matter what signal is received and backtraced by gdb. SIGSEGV just
happens to be the easiest one to do that with ...
