[ODE] cylinder geom problem (ODE INTERNAL ERROR 1)

This assert appears to be triggered by there not being enough (or
zero) free slots in the contact array you pass to dCollide. Try
raising the number of max_contacts to something like 8/16

What are the values of 'Flags' and 'Index' when this assert is triggered btw?
