[ODE] BoundsChecker

[DjArcas]

Nope nope and I think so... and I don't have *nix :)

The only thing it's warning me about is literally thousands of 'Unitialized
memory copy in swapProblem', inside SolveLCP. After a few dozen physics
updates (all my objects have gone to QNAN already), I get a crash inside
dSolveLCP, where it tries to allocate more memory:

dReal *d = (dReal*) ALLOCA (n*sizeof(dReal));

My guess is that the QNAN problem is causing all the objects to collide
inside eachother, causing me to run out of stack.



I've uploaded the purify report here:

 but, I'll be honest, large swathes of it is gibberish to me!
