Error: No source available for "__kernel_vsyscall() at 0x12d422"

After my program finishes its execution,this piece of information about an error appears on terminal:

I also debugged the code nothing seems wrong except after returning "0" to OS this error messege shows up:

Code:

No source available for "__kernel_vsyscall() at 0x12d422"

I have no clue if this has something to do with my code or OS.Any ideas?

Well the info you need is in the first line.
> *** stack smashing detected ***

You overran some local variable (of main), trashing the stack which would take you back to the OS properly.

Look carefully at any arrays you have.

Thanks for your help.Though,I didn't exactly understand it.What do I need to look for?

Somewhere, you have done something like this:

Code:

int main()
{
    int array[3];

    array[0] = 1;
    array[1] = 2;
    array[2] = 3;
    array[3] = 4; /* Whoops, I went off the end */

    return 0;
}

Look at whatever arrays are declared at the top of main(). Somewhere, your manipulations of those arrays are incorrect.

Alright,thank you very much!
