In my OCaml program, I have a large static 2D array, where the inner
array contains pairs of strings. The inner arrays each have 2**9
elements, the outer array has about 1700 elements.
The strings are about 90 characters each.

If I compile it with ocamlc 4.07.0, everything is fine. With ocamlopt,
I get a segfault.

What limit am I hitting to get the segfault?

Looks like stack overflow to me.
