[ODE] world step on linux not working?

[Fabian Mathews]

hi again,

i tired building with double precision, and again as debug build.

i dump the position of my ode object to file:

car position: nan nan nan
car position: nan nan nan
car position: nan nan nan
car position: nan nan nan

some ode spam, could be the problem?:

ODE Message 2: vector has zero size in dNormalize4()

ODE Message 2: vector has zero size in dNormalize4()

ODE Message 2: vector has zero size in dNormalize4()

ideas?

It is very likely that you have a bug in your code,
look (if possible)

Also, check if you compiled everything with the same
level of precision (float,double)
