Well, I simply cannot give him a debug version of the executable to run.
Perfect, ask for a crash dump (those infamous *ix core files), and make
sure to tell customer to change shell process limits (coredumpsize etc)
first so it's not truncated.
You then load this core dump with your -g compiled version and will be
taken straight to the black hole.
It works because both binaries are exactly identical - the additional
symbol and debugging information is in different segments of the
executable.
