I don't normally bump things, but this has been unanswered for over two weeks, so I think it deserves it. I really can't believe that rotation sensors would be this broken, and yet, I can't see anything wrong with my code. It really is odd... (14 years ago, 24-Jun-10, to lugnet.robotics.rcx.legos)

Hi, I've tried using the latest BrickOS and the latest BIBO with patches (from here: (URL) both with the same result.

While working on Bibo, I observed some unexpected differences between GCC 3.4.6 and gcc 4.4.1. Specifically, one of the XS Lisp demo programs that is fine when built with 3.4.6 is too large (section .bss not within region ram) when built with 4.4.1. (...)
