Bonjour à tous,

Voici mon petit souci, j'utilise sous F15 blender 2.60 (même souci avec la 2.60a) et j'ai des plantages aléatoires lors de sélections d'objets...

Du coup, pour espérer avoir plus de détails sur ce soucis, je lance blender via le terminal en mode debug
[PapsOu@Salon blender]$ ./blender -d
Je sélectionne quelques objets les uns après les autres, et hop, j'ai une belle erreur de segmentation :

auriez-vous des pistes à creuser pour déterminer d'où vient le problème et comment le résoudre ?

Est-ce que tu as installé les debuginfo (par le dépôt ad-hoc) ? peut-être qu'avec les bons flags le mode debug sera plus parlant ?

Je cherche actuellement à installer ce « debug info »... Sans succès pour l'instant.
Bon, avec GDB j'ai quelque chose de beaucoup plus bavard, mais incompréhensible pour un non initié comme moi... Si ça parle à quelqu'un ?

Fait que c'est pas un vrai debug. J'ai pas de Fedora sous la main mais avec ça il devrait installer ce qu'il faut :
yum install blender-debuginfo --enablerepo=*-debuginfo
Encore plus bavard avec le paquet suggéré (mais je pense pas que se soit la bonne release (le paquet blender de F15 est le 2.49, là j'ai mis la version officielle 2.60)

Je n'ai pas compilé cette version, j'ai seulement chopée la version x86_64 sur le site officiel. Mais ça le faisait aussi avec la version compilée (chopée via leur svn).
Je vais voir pour poser un bug chez eux, mais vu le caractère aléatoire, j'ai bien peur qu'il ne passe aux oubliettes directement... Enfin je testerai ça d'ici peu.

Merci pour le coup d'main.
Rapport de bogue à Blender.

Pas de problème visible avec la version de F17 (la dernière n'est pas encore là pour F16 😢).

Rectification. C'est donc bien un bogue de blender 2.60a, car je viens d'avoir le même problème avec le paquet de fedora 17...
