Brad Roberts <braddr puremagic.com> 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.

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