Stephen, can you also post some stack traces showing where it's looping? I can work
on separating out the syntax patch but i'd like to see some of the traces so i can be
reasonably convinced that this is indeed the location of the problem.

infloops for me in my current process, but not if I take out the call
to message-mode, and (unfortunately) not at all in a fresh invocation
with -vanilla. I suspect a problem with the syntax table, but that's
as far as I'm going to get today.
I would appreciate it if people would let me know what results are for
a fresh invocation -vanilla, and also if Gnus users with a well-used
Gnus invocation would see if that gives them an infloop. Also in
21.4.recent.
Other suggestions?
Ben,
You and/or Jan Vroonhof fixed a bunch of bugs in the syntax table code
in spring of 2002. That patch was never applied to 21.4, because it
was part of one of your mega-patches (message id
adrtpho9.fsf(a)xemacs.org) and it was a little too difficult to tease
out of the message. Can you please investigate this gnus infloop
problem in 21.4? Stephen and others think the problem may be related
to the syntax table - I'd really like to robustify that in 21.4, and
I'd even be potentially willing to risk temporarily de-stabilizing the
21.4 branch in order to get that ultimate robustness.
Please let me know your thoughts on this.
Thanks,
Vin

If what you are talking about is what I think you are talking about,
this might be what you are looking for...

I still have the core file and the binary that created it if you need
anything further.

I'm still having no luck. I'll try to get a stack trace, but I'm not
running under the debugger---I'll have to see if I can attach to the
running process.
A number of things that should be clarified:
(1) I have NOT been able to reproduce any such bugs in 21.4, probably
because it needs to run Gnus for a while. The "running process"
is a 21.5 (Installation attached below). Note that it's CVS as of
September.
(2) The reason I suspect the syntax code is because that's the obvious
way I can see that Message Mode would affect regexp processing,
specifically for ?_ with a \w in the regexp.
My suspicion about the syntax code is not the code that Matt
Tucker ported, it's that I suspect that Message mode depends on
inheritance of syntax tables which we don't support.
