--- Comment #1 from Tim Shen <timshen at gcc dot gnu.org> ---
As I cross checked, boost 1.66, libstdc++, and python3 have the same behavior,
only libc++ is different from the rest.
I haven't checked the ECMAScript spec, but I suspect that it describes the
boost/libstdc++/python behavior, only because it's more efficient, not less
confusing.
I know exactly how libc++ produces this result. It creates an empty
match_result during each repetition ("*" operator). It's less confusing but
much slower.
