One common problem with large number of bodies is running out of stack
space. You can increase the stack space available to your program by
running 'ulimit -s unlimited' from your shell, before you start your
ODE program. But if you run python under gdb or similar you'll be able
to see exactly which function is crashing (the stack problem is
dSolveLCP).
