Bug description

Full_Name: Hideo Bannai
Version: 3.06
OS: Compaq Tru64 UNIX V5.1
Submission from: lavender.ims.u-tokyo.ac.jp (133.103.74.218)

Hello,

This might be related to #1350, but in my case it wasn't
a Linux system but a Tru64 UNIX system. The difference is that the compilation
of OCaml went fine, but when I tried to run programs which allocate a large
amount
of memory, (few hundred megabytes) I got the same 'out of memory' error.

e.g:

    Objective Caml version 3.06

Buffer.create 200000000;; (* about 200 MB? *)

Out of memory during evaluation.

I recompiled OCaml with

 #define USE_MMAP_INSTEAD_OF_MALLOC

in config/s.h, and the problem seems to have gone away...

Regards,
Hideo Bannai
