Possible Error in rsync 3.0.9

[Robert]

Hi
   I was using rsync with the following options
rsync -aPH --exclude-from=/var/tmp/ignorelist /home/me/ 
/run/media/me/ADATA\ #2/rsync-me/
and I was creating a copy of a home directory on my Linux machine. It 
went along for sometime (some 30,000 files) when it stopped with the 
following message.
--->

Desktop/OSme/Web-Site-Backups/backup-5.4.2014_15-11-43_linux014.tar.gz
   4288446464  78%   32.15MB/s    0:00:36
rsync: writefd_unbuffered failed to write 4 bytes to socket [sender]: Broken pipe (32)
rsync: connection unexpectedly closed (1964386 bytes received so far) [sender]
rsync error: error in rsync protocol data stream (code 12) at io.c(605) [sender=3.0.9]
[root at puter ~]#

<---
   I suspect, because the 4,288,446,464 is so close to 2^32 that it is 
32 bit limit error of some kind.  It happened twice on the same file.  
The version I am using is rsync.x86_64 version on Fedora 21. It appears 
that although it says it is a 64 bit version something in the code must 
be limited by 32 bit values.
   I could be off track here but I don't think so.  I do not know how to 
raise a Possible Bug Report so I post my concerns here. Thanks...
Robert
