DocEx error trying to read section 'Table of Program Output Facilities']
barmar after originally failing to reproduce the error (as seemed to be the
consensus from most individuals) managed to find the error. I don't
understand why an error that Symbolics and many others couldn't reproduce
would seem so deterministic: only requiring an Ivory machine and trying to
lookup any of several specific document sections. I thought I'd share
barmar's findings with the net. I'm unable to fix my machine because I don't
seem to have the source for this function.

Found the bug; it only occurs on Ivory machines when looking up a flavor
method. SAGE::ARGLIST-FOR-FUNCTION-RECORD contains the following:
(cond (function-standin nil)
((atom function) nil)
((eq (car function) 'defun-in-flavor) 2)
((member (car function) flavor:*fdefinable-method-types*)
The bug is that there's no #+imach variant in the last clause. This is
causing the COND to return what MEMBER returns, which is a tail of
*FDEFINABLE-METHOD-TYPES*, rather than an integer or NIL as expected.
