It's a brilliant idea. Ubuntu did it :-) It uses the Linux kernel's
core handling support, and is called apport.
https://wiki.ubuntu.com/Apport
You'll notice a bit of a way down that there's GDB output; in this
case it comes from a core dump, but I'm pretty sure the same kernel
hooks can be used to take control before the core is dumped. I'd have
to check.
