Thread: Trying to generate a bus error

Hi. I am trying to generate a bus error using unaligned memory but it's not working. I tried it myself first but couldn't get it to work, so I used the code from the wikipedia entry:

Code:

#include <stdlib.h>
int main (void) {
  int x, *iptr;

  char *cptr;

  cptr = (char*)malloc(33);
  if (!cptr) return 1;

  cptr++;

  x = *cptr;

  iptr = (int *) cptr;
  x = *iptr;

  return 0;
}

It seems to run fine. The version of gcc is 4.1.2. It is supposed to generate a bus error so why isn't it?
