It is most definitely a bug.  I'm surprised about the 0 instead
of a NULL there.  The later would easily be explicable by 
forgetting to call layout_decl.

My only guess is that this decl had an incomplete type at some
point.  Is the function in question a template?  I could see as
how maybe we need to call relayout_decl after instantiation, or
simply re-order how the parm_decls are created.
