Turning on Core dumps

lostinvietnam · 02-03-2007, 10:20 PM

Hi.
I'm using gdb to debug a binary with a stack overflow. The segfault doesn't generate any core file for me to debug against. Does the ulimit command allow me to turn on core dump generation for third party apps or does it just control core dumps generated by the kernel? How can I get my segfault to dump core?

Thanks.

Ulimit will change the core dump size for user shells running the program. You may need to check if there is a PAM imposed limit as well. Check /etc/security/limits.conf.

Use coreadm command to enable the core file generation

You can use "ulimit -c xxx" to open the core dump. And press "ulimit -a" to have the more help.
