Help GDB & Watchdog...

[V. Rajesh]

Hi,

I face a problem. If anyone can help me, it will be great.

Basically, I want GDB to stop my program if it has gone into
an infinite loop.

I tried "set watchdog" command to achieve it. But, it doesn't
seem to work. I don't know whether I am doing it correctly.
Please help me.

Example:  test.c - program runs into an infinite loop

int main()
{
   while (1);
}

$ gcc -g test.c

$ gdb a.out

(gdb) set watchdog 3        /* I want GDB to stop the program if
                               does not terminate in 3 sec. */

(gdb) run
....                       /* It hangs. Does not termite after 3 sec */


I tried many combinations. But, it doesn't work. 

Thanks for your help,
Rajesh
