Salut,

cela provient du fait que tu passes par le Marshaling c'est-à-dire que 
tu transformes ta donnée en une chaîne de caractères. Or, celles-ci ont 
une taille limite (voir module Sys pour la valeur exacte) d'où le seg fault.

A mon avis essaye d'écrire directement ta valeur dans le fichier avec un 
output_value ou bien utilise "ocaml xml" pour lire/écrire des données 
sous le format xml (c'est plus bcp lent mais cela passera à coup sûr la 
limitation des 30 Mo)

Amicalement,
Frédéric Gava
