On darwin1(0|6) ulimit gives

stack size              (kbytes, -s) 65532

and the environment variable OMP_STACKSIZE is empty. 

Note that on darwin10 (revision r245900) the reduced test succeeds with
OMP_STACKSIZE set to 80k and for smaller values I get an error

libgomp: Stack size larger than system limit

at run time.
