Sorry, I’ll let this as an exercise for you.  :-)

I’d expect it to be reproducible on any recent x86_64-linux-gnu machine
(this was with Glibc 2.11.1 and GCC 4.4.3, FWIW).  Perhaps Valgrind can
provide hints, too.

The best would be to install Nix and Nixpkgs/trunk on an
x86_64-linux-gnu machine, patch Nixpkgs with the attached patch, and run
“nix-build -A rcs -K”.

It takes time, though, and may be inconvenient if you don’t plan to use
Nix otherwise.

Thanks,
Ludo’.
