[ODE] Crash in test_boxstack on Mac OS X

[Timothy J. Wood]

   I just did a clean build of the head of CVS with double-precision and 
debug mode.  I'm using the Dec 2002 Dev Tools package and the latest 
X11 from Apple.

   If I run the box test and hold down 'x' so that a huge number of 
composite objects are created, I get a crash in a couple different 
places.  It seems fairly likely that ODE is blowing the stack with 
alloca usage.  Is this something that is known already?
