Thanks.  This is the problem; tindent should never be less than zero.
I'm not sure why I'm not seeing it; it might suggest the structure with
the function in it is already corrupt at the point where you run

The following patch should stop the crash (so it's probably worth
having) and report at the point where it first becomes confused, though
it doesn't address the underlying problem.

With latest cvs, it still crashes, but differently.

Don't know if it would help but here's the zwc file too,
