[syslog-ng] syslog-ng 3.5.1 - question about flags(final)...

[Balazs Scheidler]

Hi,

A fix and test is available on this branch:

https://github.com/balabit/syslog-ng/tree/3.5/f/cfg-tree-final-fix

I'd really appreciate any further testing and whether the 3.4/3.5
behaviour is consistent with 3.3.

Algernon should pick these patches to the stable branches shortly,
here's the pull request for that:

https://github.com/balabit/syslog-ng/pull/26

Thanks for the report.
Bazsi
