Right, I'm sorry I wasn't clear, but that's what I meant.  In clang we  
try really hard to never create invalid ASTs, even for invalid code.   
To mark the field decl invalid, we first have to force the type to  
something valid, create the decl, then mark the decl as invalid.  I  
completely agree with you that this is the right thing to do in this
