Using the following compile time testcase (only for x86-pc-linux-gnu):
typedef struct Parent
{
  long long m;
  int *scratch;
  void * __attribute__((aligned(8))) this$0;
}Parent;

int f[sizeof(Parent)!=24?-1:1];

I found that this started to be rejected between 2004-06-22-trunk 
(#470) and 2004-06-24-trunk (#471).

I used Phil's regression hunter: <http://www.devphil.com/~reghunt/>.
