We use rsync heavily for software distribution.  When we upgraded from
2.5.7 to 2.6.2 (platform is NetBSD 1.5.4 and 1.6.2), we begain seeing core
dumps on one machine (see below).  I've installed rsync-HEAD-20040606-1916GMT
on that machine and the problem does not seem to be happening, at least for
my test case that was provoking the crash n 2.6.2.

We can submit the core file etc. if needed.
