--- Comment #1 from kinke <kinke at gmx.net> ---
This seems to boil down to the usage of `program_invocation_name` on Linux to
obtain the name of the executable file (though that hasn't changed in the
linked druntime PR). It's apparently just `argv[0]` and so not really robust.
Not sure if BSD's `getprogname()` is better in this regard. Too bad
`std.file.thisExePath()` is in Phobos and thus not usable.
