digitalmars.D.learn - Debugging compiler crashes?

Hi,

I have a body of code which makes the compiler frontend segfault.

Is there some automated tool which will help me produce a minimal
testcase so I can file a bugreport? The body in question is fairly
large, just posting that to a bugreport doesn't sound like a good idea
to me.

Thanks,

Thanks, that sounds like just the thing I need.

However, it doesn't seem to compile for me:

wouter carillon:~/code/d/DustMite$ dmd -ofdustmite -release *d
dmd: glue.c:542: virtual void FuncDeclaration::toObjFile(int): Assertion
`semanticRun == PASSsemantic3done' failed.
Aborted
wouter carillon:~/code/d/DustMite$ 

... and I'm not yet that fluent in D to understand what's going on. Any
ideas?

(dmd 2.059, in case that matters)

... the order of files matters? Yuck.

Oh well.

Anyway, this helped tracking the problem down, and I've now filed a bug:
