It's never a bug, it's a 'unknown software feature'. :)
Long ago, each preprocessor had thier own parsers within them. Now things are
changing and moving to a much more standardized method.

I would suggest upgrading to 1.8.7 if you can. There was quite a bit of
change in the parsing code, and in the stream4 processor. I'm not saying this
will 'fix' everything, but it would put you on the most solid codebase to work
If you do update to 1.8.7, you'll want to also set the ttl_min value. There's
been some recent postings on that, so check the archives for the discussion
and use of this. Note: It's for 1.8.7, and not 1.8.6. :-/
