These issues were fixed a while ago. Use the latest "daily" release (or
build for yourself from depot).

The missing context may tell another story but, I don't see *anything* wrong
with this line.

Do you have a sample grammar that demonstrates what you feel is the problem
here?.

I expected you might have sent me a grammar as you did previously.

Johannes, post a sample grammar and we'll try to reproduce the issues. Many
seem to relate to issue that were fixed already (?).
