The stack overflow problem is typical for ode in windows. Ode's solver uses a 
rather large matrix to solve the contact joints. When you have a lot of 
collisions the stack gets to large and you get a stack overflow. 
The solution to this is to not generate so much contacts or use the stepfast 
functions. The stepfast functions are covered in the documentation.  It means 
slightly less precision but huge speed gain and less memory use.
