Problems with starting asterisk

Hi i’m novice in asterisk,
I have installed asterisk1.2.12.1 (under RedHat Enterprice Linux AS3)
I have no errors while compiling modules.
But when i start asterisk i get some problems:

[user@server bin]# asterisk -cd
Parsing /etc/asterisk/asterisk.conf
Parsing /etc/asterisk/extconfig.conf
Segmentation fault

How can i fix this problem???

Thanking you in anticipation

can you fix it … yes. if you want someone to help you’ll need to turn on debug logging (look at /etc/asterisk/logger.conf) and post the output for a failed start here.
