Use whatever command is appropriate for your shell to find out what your
resource limits are set to for stack.  For bash, it's "ulimit -s":

    % ulimit -s
    8192
    %

So by default, once I use more than 8 megs of stack space, I crash.

System administrators usually put limits on per-user reasources so that
one person's process can't wedge an entire machine.
