Have you tried this with dmd itself?  It's unlikely that this is a gdc 
specific bug.

I was under the impression that the things enclosed in debug{} and version{} blocks had to be complete expressions. In you example, you enclose the 'case:' keyword and I'm not sure that is supposed to be allowed. For example, this works ... void main( char[][] args ) { switch( args[1] ) { case "--foo": case "-f": debug { foo(); } break; case "--bar": case "-b": version( bar ) { bar(); } break; default: foo(); bar(); break; } } Anyhow, I'm sure that a better message would have helped this situation. -- Derek (skype: derek.j.parnell) Melbourne, Australia "Down with mediocracy!" 3/04/2006 2:44:27 PM

It's a frontend bug.  Sorry.  I'll check against dmd in the future.
