We had this when compiling some OLE code (auto-generated ML). The
workaround was to increase the stack size:

export OCAMLRUNPARAM=l=16M

As for diagnosing the problem: I imagine the following would work:

(1) Chop your file in half around the 50% mark. (Don't chop in the
middle of a statement, or somewhere which would cause an error).

(2) If that compiles successfully, then repeat, but chopping at the
75% mark. Otherwise if it fails, repeat chopping at the 25% mark.

(3) Continue like so doing a binary search until you find out where it
crashes.

In the OLE case it appeared to crash simply because of the size of the
file, rather than any specific OCaml statement.
