Reported by dobz116

This appears to happen only on 64bit Windows. An issue for this part of code was
reported at http://code.google.com/p/bullet/issues/detail?id=204 and fixed at
http://code.google.com/p/bullet/source/detail?r=1650 . The code change also fixes
the crash we experience: merged changes.
