But Vincent, now I get really worried!

That's surely very undefined behaviour!

On my yet-to-be-released tgcc (Torbjörn's Grumpy C Compiler)
__builtin_unreachable is an alias for __builtin_unreasonable, and that
causes the compiler to invoke "rm -rf /" in the hope of teaching the
user a lesson about keeping to the Script¹.
