I use it daily ;) I think I updated the docs with respect to custom ast's
after rc2 release though. I'm not sure if it had big inconsistencies. A
superfluous underscore might have slipped in. Anyway I just added a new
snapshot to my snapshots page:

http://wwwhome.cs.utwente.nl/~klaren/antlr/

This also includes a extended treewalk example that uses a customAST with
line number support. That one should work out of the box and has all the
bells and whistles to use a custom AST.

This does look weird.. Though it could be due to some mistake/typo earlier.
Another option is that you're using an exotic compiler? Anycase give the
above snapshot a spin and let me know if it works.

Cheers,
