Iain Buclaw <ibuclaw at gdcproject dot org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution|--- |FIXED --- Comment #7 from Iain Buclaw <ibuclaw at gdcproject dot org> --- It required removing all system includes from all dmd frontend sources, but I think this OK now. I have verified that gcc_assert() is being called now instead of assert().
