What kind of exception was that? From what I can see it should never fail...

There is no problem with commiting to trunk, even when there is
separate branch - we should be able to merge the branches later
without problems, especially that optimizer branch probably won't
touch the same code as your changes.

The best way would be to skip incorrect parser trees on all levels
(parser, hierarchy building) if possible. Here probably it could be
solved by checking the value and just marking error, but not finishing
the whole analysis.
