[resending to the list, too, with more information on what I've tried to
reproduce]
Please take everything to the berlios.de lists (you'll need to
subscribe there) - we plan to leave the ccil.org lists since nobody has
administrative access to them any more.

Hi,
I noticed that my fetchmail was segfaulting at the very start of a
particular mail message, with this trace:

It is downloading mail from POP3.
I seem to be unable to reproduce this. I've tried the POP3 modules of
Dovecot 0.99.14 and some older Courier-IMAP.
What upstream server software are you using,
who built your fetchmail version,
and what is your .fetchmailrc?

What has "msgblk.headers" got to do with "line"? I'm not particular fond
of such skewed checks, they'll come back some day to bite us.
