I've debugged this until a failing optMatch call with seemingly correct
arguments.
https://github.com/dlang/phobos/blob/7a2732e4b06d6684a717a756c20e271e9ede2812/std/getopt.d#L842

When converting optMatch to a template the bug goes away, so it might be some
incompatibilities with the pre-compiled binary function shipped with
phobos-2.077.0.
