I've beeen playing with this in an attempt to find a workaround, and
it's such a mess that I don't think it's worth it.

Consider this:

---------------------------------------------------------------------
#include <stdio.h>

class Boof
{
  int arse ()
  {
    return 25;
  }

  void *prickle;
};

class foo : Boof
{
  public: long long i;
};


int main ()
{
  foo f;
  fprintf(stderr, "offset: %d\n", (char *)&f.i - (char *)&f);
  fprintf(stderr, "alignof: %d\n", __alignof__(f.i ));
  return 0;
}
---------------------------------------------------------------------

Run it on x86, and you get:

offset: 4
alignof: 8

We can't leave it like this.

Andrew.
