Summary

0002306: resource consumption when compiling arrays

Description

Full_Name: Achim Blumensath
Version: 3.07
OS: Linux
Submission from: igloo.labri.fr (147.210.9.44)

I've noticed that ocamlopt uses a lot of time, memory, and
stack space when compiling arrays. It seems that some of the
functions used to compile arrays are not tail-recursive.

I have one file solely consisting of about 2000 arrays of
size 256 containing strings, integers, or pointers to some
of the other arrays. To compile this file, ocamlopt needs
several minutes and between 16k and 32k of stack space. With
256 MB of memory it even starts swapping at the end of the
compilation. I can provide the source code if needed.
