////////////////////////////////////////
Works in DMD 2.085 but not newer.
Bisecting shows that the error message begins manifesting when it was
introduced ( https://github.com/dlang/dmd/pull/9425 ), however debug versions
of DMD have been failing with an assertion failure before that change. The
assertion failures began after https://github.com/dlang/dmd/pull/5500 .
