malloc/free question..

[I Rattan <ratta1i@xxxxxxxxxxxxx>]

Under Linux with gcc version 4.4.6 (Debian 4.4.6-11)

The following code:

int main(int argv, char** args)
{
  int *arr;
  int n;

  n = 10000000;

  arr = (int *)malloc(4*n);
  free((void *)&arr);
  exit(0);
}

generates warning:

	err.c:14: warning: attempt to free a non-heap object 'arr'

any ideas?
