DragonFlyBSD

It would have been nice to contact sendmail.org to tell them about it...
Anyway, a patch is attached.

:I have sendmail randomly coredumping on signal 11 on my freshly upgraded
:dragonfly 1.12 box. It looks like the bug Matt fixed, so I spent some
:time making sure that patch to main.c actually found it's way into this
:binary. (That doesn't mean I actually succeeded at this but it's quite
:likely I did.)

:#1 0x0809b565 in smtp (nullserver=0x0, d_flags=0x80fe18c, e=0x80fc740)
: at /usr/src/usr.sbin/sendmail/../../contrib/sendmail-8.14/sendmail/srvrsmtp
:.c:3789
:#2 0x080aff32 in main (argc=5, argv=<value optimized out>, envp=0xbfbff6f8)
:at main.c:2641
:
:I've placed the corefile and the binary on leaf in my "crash" directory,
:for perusal of better eyes than mine. Thanks in advance.

Hell.  It's the same bug, but in a different location.

Fetch this patch file and apply it in /usr/src/usr.sbin/sendmail,
    then recompile sendmail.  Tell me if that fixes the problem.

Ach.  two more places.  I only caught the second one.

Don't worry, contacting sendmail was next on my list.  Can I assume
    you will take care of it, Claus ?

I should have checked the other use cases when I reported the
    original bug.

Yes, it is in our CVS tree for a while already (currently in alpha

Someone else reported one of those and I found the third. That
should be all...

Well actually I just did a "cvs up -Pd" in /usr/src/usr.sbin/sendmail
to pick up your commits.

With the previous sendmail binary, coredumps happened within 15 minutes
of starting the server. I've been running with the current binary for
approximately one hour with no coredumps.

I also had a user who had problems sending mail under the old binary.
This user has run the same test case and found no issues or problems.

Yah, I decided it could go in immediately when Claus posted the
    more comprehensive patch.

I am going to roll 1.12.1 on wednesday.  There was another MFC that
    went in a few days ago that we also want to get in there, as well.
