It's a bug.  Fixing it will require a wholesale code revision, however
(see my prior postings about redesigning the function call interface).

This is something we need to do for 6.6, IMHO, not only because of
the NULL-argument issue but also because it will solve the portability
problems that are being created by the existing fmgr interface (Alpha
bugs, need to dumb down to -O0 on some platforms, etc).  I've been
trying to summon the will to get started on it, but other things keep
getting in the way...

Yes, 8.  I'm not planning to do anything about that in the near term.
Even just making the limit configurable would be a lot of work :-(
