Physics engines

[mds]

Here the chipmunk demos for Windows. OpenGL and GLUT the only dependencies.

It certainly is compiled, but an arithmetic overflow occurs at startup. Physics dovno not been updated, and of course with the current version of the compiler I think these errors are possible. How can I fix this? Or what other options there are, that would not suffer, and to connect the physics and can already be working.
The very error occurs here:

if options.drawShapes then
  begin
    cpSpaceHashEach(space.activeShapes, drawObject, space);
    cpSpaceHashEach(space.staticShapes, drawObject, space);
  end;

in the funtion draw by drawSpace module
