Mingw Ocaml-3.08.2 "Program too big to fit in memory"?

[Dominic Cooney]

[-- Attachment #1: Type: text/plain, Size: 482 bytes --]

I built Ocaml-3.08.2 with Cygwin Mingw (all downloaded today) and all of the
binaries (e.g. ocamlc.exe, ocaml.exe, ocamlopt.exe, etc.) report "Program
too big to fit in memory". All of the opt.opt binaries (e.g. ocamlc.opt,
etc.) and OcamlWin.exe seem to work fine (although OcamlWin can't spawn
ocaml.exe, of course.) The machine has 2 GB physical memory and is very
lightly loaded (page file usage is about .5 GB).

 

Has anybody encountered this problem?

Perhaps you have *too much* memory.

Your situation reminds me of problem I've had with > 2GB disks and older installation programs who computed remaining disk space with 32 bit integers and thus failed. OCaml maybe computes remaining memory with 31 bits so 1 GB is the max (on 32 bit machines) ?

I think the binaries are corrupt. Here's the output of dumpbin on ocamlc.exe
and ocamlc.opt.exe (note that ocamlc.exe doesn't work, and ocamlc.opt.exe
does work):
