Alors réponse à moi même.
Après recherche le seg fault peut-être du à une mauvaise comptabilité de ram. Horreur mes deux machines avait des barretes de ram que j'avais installé...
Oui, mais... J'ai testé le crash sur une autre machine, et les softs, ainsi que blender plante de la même façon.
J'ai pu préciser également les circonstances dans blender qui font que ça seg fault.
Dans ma scène j'ai par exemple une ico sphère au dessu d'un cube, lui même au dessu d'un plane. j'englobe le tout d'un autre cube qui sera mon domaine pour... le simFluid (l'ico sphère étant le fluid, et les deux autres objet les obstacles)
Sauf que, moi, et c'est la àù ça ne va plus. Je supprime les faces du cube domaine. avec del> only faces.
Ce qui nous donne un cube en wire. Je lance le bake.
Et c'est le crash.
J'ai un peu trainé sur irc sur des chan spécialisé pour voir.
C'est peut-être pas le bon endroit mais je paste le resultat de la commande gdb ./blender pour le binaire blender 2.49b donc, téléchargé via le site, pour linux x86.
