--- Comment #6 from Seb <greensunn...@gmail.com> --- > it's resolved in stable. https://github.com/dlang/phobos/pull/6342 Also note that DMD nightlies are currently broken and haven't been built since the end of February (in case you tried this with run.dlang.io) In any case I hope that 2.079.1 will be released soon. --
