Description:
------------
After update of php from 5.5.9 to 5.5.10 and apache from 2.2.26 to 2.4.7 rsync got falling while synchronization process.

Test script:
---------------
array($out);
exec("rsync -auzvvvvvvvvv --delete --temp-dir='bad/' --exclude='/bad' --exclude='.htaccess' ./generated/ $host:/some/dir/", $out);


Expected result:
----------------
Synchronization have to executed.

Actual result:
--------------
Synchronization falls at some stage without actual transferring of a files with error code 13. $out contains reference to a line 244 of a rsync's log.c. Here it:

static void filtered_fwrite(FILE *f, const char *buf, int len, int use_isprint)
{
	const char *s, *end = buf + len;
	for (s = buf; s < end; s++) {
		if ((s < end - 4
		  && *s == '\\' && s[1] == '#'
		  && isDigit(s + 2)
		  && isDigit(s + 3)
		  && isDigit(s + 4))
		 || (*s != '\t'
		  && ((use_isprint && !isPrint(s))
		   || *(uchar*)s < ' '))) {
			if (s != buf && fwrite(buf, s - buf, 1, f) != 1)
				exit_cleanup(RERR_MESSAGEIO);
			fprintf(f, "\\#%03o", *(uchar*)s);
			buf = s + 1;
		}
	}
	if (buf != end && fwrite(buf, end - buf, 1, f) != 1)
		exit_cleanup(RERR_MESSAGEIO); // <<< *** This is line 244 ***
}
