gnus is hanging on cite-parse

gnus is hanging on cite-parse

[Pavel Zhukov]

Hello,

I have problem with gnus displaying some messages like described in [1]
In my case traceback looks like [2]. As a workaround I use cite regexp like (setq message-cite-prefix-regexp ">") but it's not a solution.
The problem occurs if I try to open this email https://lists.isc.org/pipermail/dhcp-users/2017-September/020820.html for example (and many many others). 

Can somebody point me out what's wrong with the citation/regexp and how to fix that? Or how to debug the issue further.

Debugger entered--Lisp error: (quit)

I got the email from
<https://lists.isc.org/pipermail/dhcp-users/2017-September.txt.gz>
and tried reading it using Gnus, but no such a problem happened.

The operand of `looking-at' is the same as the one I use, that
is just the default value of `gnus-supercite-regexp'.  Well,
what does happen when you evaluate this form at every beginning
of line one by one in that article body?

M-: (looking-at gnus-supercite-regexp) RET

You may also want to look up edebug, edebug-defun
to step trace want is going on, there.
