That's one of the benefits of writing cross-platform.  Not every bug
can be flushed out on every platform, whether by circumstances/fluke
or availability of tooling (including from the toolchain or external).

A program that run son Linux and Mac, and is checked with Valgrind on
Linux, gives me a bit more confidence than a Mac-only similar program.
