I'm using Visual C++ 6.0, so it's not just that :)
I was idly suspecting the compiler - you get different results in =
release and debug builds.

Guys, what compiler are you using?
I'm working on a car module with hinge-2 (like most people here I =
guess) for some time now. I had some problem at first... (Mainly because =
our engine is left handed because of DirectX, and ODE natively right =
handed because of the OpenGL renderer.) Anyway, with the matrix =
conversion in place and all, things turn allright. That was with Visual =
Studio 6.0. We recently attempt to migrate to Visual 7 and ODE seems to =
be numerically unstable with positions values becoming QNAN quite easily =
and all. Anyway, I haven't investigated the problem much, but maybe =
somebody happen to have the exact same problem...
