Re: die__process_function: tag not supported (INVALID)!

[Bruce Korb <bruce.korb-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

I would happily step through the code -- if I knew what to look for and
where to set break points.  But I don't.  The first call to die__process_and_recode
didn't die, so I don't know what I'm looking for.
