[GabrielDum]

Cette erreur arrive-t-elle avec la version de base ? Je crois pas avoir testé avant de modifier. C'est peut-être juste une erreur de threading avec la librairie graphique, causée par le ralentissement lié à valgrind ?

[GabrielDum]

Pour reproduire : valgrind --track-origins=yes ./main
