Probleme execution : segmentation fault in _dl_fini ()
Bonjour,
j'ai crée un executable nommé test-toto.exe.
Lors de l'execution de test-toto.exe, j'ai un "segmentation fault".
Je lance donc gdb et j'obtiens comme message d'erreur après le run :
Code:

| Program received signal SIGSEGV, Segmentation Fault
[Switching to Thread 0x2b6b149442b0 (LWP 12975)]
0x00002b6b131e7c76 in _dl_fini () from /lib64/ld-linux-x86-64.so.2 |
Lorsque je fais un ldd de mon executable, j'obtiens les informations suivantes:

La derniere information que je peux donner est que la librairie "libfaketechdata.so" consiste en une dummy librairie que j'ai compilé hors du makefile principal et j'ai rattaché ensuite à la compilation principale.
Pour générer cette librairie, j'ai effectué la commande de compilation suivante :
Code:
gcc faketechdata.c -shared -fPIC -o libfaketechdata.so -D__UNIX64__ -I../Include ......
Pour information générale, je suis sur un Opteron Suse9.1 SLES10
Avec tout ceci, est ce que quelqu'un pourrait me dire d'où vient mon segmentation fault car je ne vois pas trop l'origine du probleme.
Merci
Ludovic
