Issue ID: 17114 Summary: DMD 2.073.0 Error: undefined identifier '_arrayExpComSliceAndass_k' in module 'app' Product: D Version: D2 Hardware: x86_64 OS: Linux Status: NEW Severity: regression Priority: P1 Component: dmd Assignee: nob...@puremagic.com Reporter: viserion.thr...@gmail.com With DMD 2.073.0 I am now getting compilation errors when compiling the code contained in https://github.com/Soulsbane/ctoptions/blob/develop/source/ctoptions/commander.d ./libs/ctoptions/source/ctoptions/commander.d(187,28): Error: undefined identifier '_arrayExpComSliceAndass_k' in module 'app' ../libs/ctoptions/source/ctoptions/commander.d(187,28): Error: undefined identifier '_arrayExpSliceAndass_k' in module 'app' source/app.d(232,13): Error: template instance app.main.Commander!"app".Commander.process!() error instantiating It is failing on this code: alias member = helper!(__traits(getMember, mod, memberName)); The 'mod' variable comes from: alias mod = helper!(mixin(modName)); This code is part of a mixin template where 'modName' is defined as mixin template Commander(string modName = __MODULE__). I have no idea what the problem is. This code has always worked before now. The only fix for now is I've done a static if to check for those function names and skip over them in that case. Hopefully that's enough info! Thanks! --
