Comment 1 Oleg Sukhodolsky 2003-10-22 02:11:04 UTC

I think this bug was fixed in 1.3.  At least, I'm able to reproduce it in 1.2
and unable to reproduce in 1.3. Although, I don't know (yet) which change fixes
it.

Comment 2 Oleg Sukhodolsky 2003-10-22 18:53:32 UTC

I think this is a duplicate of 8467 ([PATCH] Number of paren pairs limited to 
16)
(http://nagoya.apache.org/bugzilla/show_bug.cgi?id=8467).

Comment 3 Vadim Gritsenko 2003-10-22 23:13:03 UTC

Yes, you are totally right.
