Issues with fstack-protector?

I want to detect stack overflow or corruption in my code. Hence, i wrote a small program where stack overflow i开发者_开发技巧s simulated. I compiled it using the command:

gcc overflow.c -g -fstack-protector-all

However, upon executing the binary i got segmentation fault but no other information. Can anybody please help me where did i go wrong?

If ulimit -c is set to a value much bigger than zero, a core dump named core is written; you can see the backtrace via running gdb program core and then typing backtrace at the prompt.
