Hi,
I use Gnus to read from the NNTP server over at nntp.lore.kernel.org on
the group org.kernel.vger.git. When I opened one particular message on
the group today Emacs froze up completely. top reported 100% CPU usage
from it. This went on for a couple minutes until I hit C-g. The message
that triggered this has Message-id
<CAN05THQGqV4hP218hb3QXjJhQbbBCDRHgf=PAty=Ydd78a679A <at> mail.gmail.com>
and subject "Re: [Wireshark-dev] [Outreachy] Internship blog 2020"
I dug around a bit and found out the problem comes from the function
gnus-cite-parse in the following line:
(when (and (< guess-limit (+ begin gnus-cite-max-prefix))
(looking-at gnus-supercite-regexp))
The call to looking-at seems to be the problem. gnus-supercite-regexp
is:
"^\\(\\([ ]*\\(\\w\\|[_.]\\)+>+\\|[ ]*[>|]\\)+\\)? *>>>>>
+\"\\([^\"\n]+\\)\" +=="
This call works fine for most lines but at the end there is the line:
"> ___________________________________________________________________________"
I wrapped this in quotes because it freezes up this buffer as well.
Is this a problem with my setup only or do other people see it as well?
What can I do to fix it?
Thanks.
