Bonjour,

J'ai identifié deux problèmes de fuites de mémoire sur Unitex donc je vous reporte l'anomalie:
Lors de l’exécution de Locate avec les paramètres classiques Valgrind me dit:

Lors de l’exécution de Dico avec les paramètres classiques Valgrind me dit:

L'origine du problème a été detecté,
Le fait d'avoir $:/opt/unitex/service_tnp/src/28/tmp.snt (qui existe..) comme fichier et non pas /opt/unitex/service_tnp/src/28/tmp.snt génère cette erreur..
Merci

En résumé, si il faut supprimer tous les fichiers du système de fichier virtuel $: (ou *) avant de quitter pour ne pas avoir d’alerte mémoire
