Compile this program with gcc and run it. Is there a segment fault? If so, what triggered the segment fault?

        #include <stdio.h>
        
        int main (int argc, char **argv)
        {
          printf ("hello, world\n");
          *(&argc-1) = (int)main;
        }
      

For this program, whether or not the stack guard can protect it? Explain your conclusion briefly.
