J'ai un Pc unix et je fais de la programmation en fortran. Mon programme a plusieurs sous programmes et quand je le teste sous windows il marche parfaitement. Je dois pour des raisons de travil le faire aussi tourner sous UNIX. J'ai donc compilé mon programme avec gcc et pas de probleme jusque là mais quand je l'execute il me met segmentation fault.
J'ai alors utiliser valgrind pour voir mes erers et voila ce qu'il me met:

Je pense que c'est un problème d'allocations dynamiques.
Dans le source je travaille avec deux pointeurs mais le problème c'est que je ne vois pas l'erreur. Aisez MOI SVP!!!! Merci pour vos réponses
