Not random junk, but all 1s:

int recurse(int depth)
{
    char buffer[2048];
    memset(buffer, 1, sizeof(buffer));

    /* Call recursively */
    printf("%d\n",depth);
    recurse(depth + 1);
}

main()
{
    recurse(0);
}

Perhaps I need to go up a bit on the stack to trigger the
collision (i.e. go down two levels, then up one, etc.) ?!
