Are you perhaps running into a resource limit for the user who is running the applicaiton?
By default, OS X has pretty low limits:

% limit
cputime         unlimited
filesize        unlimited
datasize        6144 kbytes
stacksize       8192 kbytes
coredumpsize    0 kbytes
memoryuse       unlimited
descriptors     256 
memorylocked    unlimited
maxproc         100 

Try raising the datasize limit. In tcsh, that's as simple as saying 'unlimit'.
In sh variants, you need some specific flags.
