I have big system that make my system crash hard. When I boot up, I don't even have a coredump. If I log every line that get executed until my system goes down. I will find that evil code.
Can I log every source code line in GDB to a file?
UPDATE:
ok, I found the bug. It was nasty. The application I started did not take the system down. After learning about coredump inspection with mdb, and some gdb stepping I found out that the systemcall causing the dump, was not implemented. Updating the system to latest kernel will fix my problem. Thanks to all of you.
MY LESSON:
make sure you know what process causes the coredump. It's not always the one you started.
