Since writing this I've recompiled with zlib 1.1.4 and everything appears
smooth. Since this is intermittant, I'll send it off anyways in the hops
that
someone else may see it. It also *might* apply to the "known issues"
entry about "unexpected close." (Similar symptoms, but it may just be
a shared
codepath on the messages. Note that the dumped len in my output(4)
corresponds to the "dropped connection" size of 4 as well.)
Compiling still generates the same warnings as the "broken" version
(listed
below.)

--Original message
------------------------------------------------------
Okay, to preface... this is intermittant. It'll work for a bit, then start
giving
errors. Once it starts it'll usually continue until rebooting. I've
not done
a full test-case scenario on it, but have narrowed it down the the
"-z"
option. (system zlib is 1.1.3, if it matters.) Since the TODO list mentions
migrating away from the built-in zlib, I don't know that my running 1.1.3
matters.
Note that I put in 1 line of debug code so the dumped offsets
from rprintf() will be 1 line off.
This...
/usr/bin/rsync -avz --delete -e ssh <remote_source>
<local_dest>
produces....
receiving file list ... done
Detected an attempt to write across stack boundary.
Terminating /usr/bin/rsync.
"libsafe violation for /usr/bin/rsync, pid=25201; overflow caused by
memcpy()"
4 <= 1024? // my output, checking the len in io.c : read_unbuffered().
unexpected tag 101
rsync error: error in rsync protocol data stream (code 12) at io.c(299)
rsync: connection unexpectedly closed (324428 bytes read so far)
rsync error: error in rsync protocol data stream (code 12) at io.c(150)
Sync done!
This (no z)..
/usr/bin/rsync -av --delete -e ssh <remote_source> <local_dest>
works fine.
Upgraded to 2.5.5 to no avail.
While compiling, I receive a good number of
generator.c: In function `recv_generator':
generator.c:344: warning: comparison between signed and unsigned
type errors in various files, as well as
main.c: In function `start_client':
main.c:665: warning: unused variable `write_batch'
main.c:664: warning: unused variable `whole_file'
including...
zlib/inftrees.c: In function `huft_build':
zlib/inftrees.c:216: warning: signed and unsigned type in conditional expression
zlib/inftrees.c: In function `inflate_trees_fixed':
zlib/inftrees.c:403: warning: unused parameter `z'
Note again that running without -z works 100% of the time and currently
using -z will fail 100% of the time. Thus, the "connection aborted"
message
may be bogus.
Thanks.
