--- Comment #4 from Rainer Schuetze <r.sagita...@gmx.de> --- It seems I've messed up the defaults between Visual D and mago: you have to enable it in Tools->Options->Debugger->Mago. I think that being disabled is actually the better default as the vtable yields no additional information for most people. Unfortunately that build is also broken, as it tries to show [0] multiple times and fails. --
