patched qmail-remote crashes on ubuntu linux

[Matt Simpson <net-qmlist@jmatt.net>]

I've just installed Ubuntu Linux 6.06, and qmail patched with John 
Simpson's consolidated patch that adds auth, tls, and a bunch of 
other good stuff.  Qmail-remote crashes.  I don't have much more 
information other than the "qmail-remote crashed" message in the log.
Unpatched qmail runs ok, so the problem is apparently introduced  by 
the patch.  I've tried patch versions 6c5 and 6ca, and they both 
crash.
I run qmail with various versions of this patch on other systems 
(Freebsd and Suse Linux), and it doesn't crash. So I don't think the 
patch is "bad", but something about installing it on Ubuntu, or the 
way I installed it, seems to be causing problems.  I did get some 
compilation warnings when I compiled qmail, but I also got warnings 
when I compiled the unpatched qmail that worked.  I'm not 100% sure 
if all the warnings were the same in both cases.
Does anybody have any ideas what might be wrong or where I could look 
to figure it out?
