I''ve been digging into rails, but this one question has been a two day stumper. I''ve got a question/answer model that I''m trying to work out.

I'm sorry to report that so-far I have had the opposite experience. Some years ago, I ported binutils (via CGEN) and GCC to an

It was working before (as far as I can tell), but I freezed_edge and now... The first time I load this page, it works fine, the second time I get the superclass mismatch, the third time (and any subsequent times ) i get undefined method.
