rsync - Jul 2007 - rsync bug?? (rsync fails when -C is used).

hi, All. 

I just compiled the latest rsync (2.6.9). but I'm getting an error when
I use the -C option.
eg: 
$ rsync -aCv host1:/home/john/data/ /home/john/data
receiving file list ... ERROR: out of memory in add_rule [sender]
rsync error: error allocating core memory buffers (code 22) at util.c(115)
[sender=2.6.9]
rsync: connection unexpectedly closed (8 bytes received so far) [receiver]
rsync error: error in rsync protocol data stream (code 12) at io.c(453)
[receiver=2.6.9]

and if I remove the -C option. everything is fine. the directory structure is
very simple with no sym/hard links. and total number of files in there is about
30. running the command on local file system has no problem (replicating local
dir with -C option).

I did truss the remote sshd and see the client connected successfully. forked
child sshd which forked again and rsync exec'd:

137:    execve("/usr/bin/rsync", 0x0004509C, 0x000450F8)  argc = 6
137:     argv: rsync --server --sender -vlogDtprC . /home/john/data
137:     envp: _=/usr/bin/rsync

Both end of rsync is version 2.6.9. and both system are running solaris 9.
binary compiled with Sun's cc (not gcc).

The thing that makes me think that this is a bug in rsync is that I also tried 
rsync to another solaris 9 machine which is running rsync 2.5.0. and it works 
with no problem (with the -C option).

I goggled around.. and most people who are getting this error was dealing with
large number of file/directory.

Any info on this would be helpful.
thanks.

The remote rsync is running out of memory as it collects the CVS
ignore rules (add_rule).  Something could be awry with the CVS ignore
rules, or the machine could just be low on memory.  Please run rsync
again with -vvv (three verbose options), which will make the remote
rsync show (among other useful information) the individual calls to
add_rule, and send the resulting output to the list.

So the problem is happening on the very first call to add_rule.
That's very bizarre.  Since I can't reproduce the problem on my
computer, I can't do anything more on my side to investigate it;
sorry.  If you want to get to the root of the problem, I suggest that
you add some debug output ( rprintf(FINFO, "blah...\n"); ) to the
remote rsync.  A good first step would be to determine which of the
several out_of_memory("add_rule") calls in add_rule is being
triggered.
