[syslog-ng]Config file parsing inconsistencies

I seem to have discovered some discrepancies in the parsing of config file statements. I'm using syslog-ng 1.6.2. For example, the following: destination test { udp("10.0.0.1" port(514) localport(0)); }; results in a segfault upon startup, whereas the following: destination test { udp("10.0.0.1" port(514) localport("0")); }; works fine. I haven't gone searching through the code yet, but it seems that parsing of options is inconsisent (note 514 is not in quotes). A brief grep of some source files seems to suggest that there might be a inconsistencies on when to parse the option as a number versus a string. John
