Yes, 4 in both cases.

And here is the most reduced testcase (and it shows that the C and C++
front-ends don't agree any more which is bad):

#include <stdio.h>
typedef struct Parent
{
  long long m;
  int *scratch;
  void * __attribute__((aligned(8))) this$0;
}Parent;
int main (int argc, char **argv)
{
  printf ("%d\n", sizeof(Parent));

  return 0;
}

This is also seen on i686-pc-linux-gnu with the same results as on
ppc-darwin.  This has been broken since 20040909.
