[syslog-ng] 3.3.x conditional rewrite bug

The following will not work in the 3.3.x branch: filter f_rewrite_cisco_program { match('^(%(?:ASA|PIX|FWSM)\-\d\-\d{6}): ([^\n]+)' value("MESSAGE") type("pcre") flags("store-matches" "nobackref")); }; rewrite r_cisco_program { set("$1", value("PROGRAM") condition(filter(f_rewrite_cisco_program))); set("$2", value("MESSAGE") condition(filter(f_rewrite_cisco_program))); }; It will process a few lines and then hang indefinitely. It will process ok if the condition is taken off of the filter, so I am assuming this is a PCRE issue, though I found it made no difference to remove the PCRE requirement and use a simpler matching expression. All works perfectly in 3.2.4.
