Subject: [Bug c/24691]  New: attribute aligned is silently ignored or program is miscompiled

This program shows a bug: either attribute align is being accepted when it
shouldn't be, or it is being accepted but not doing it's job:

int foo() {
  int __attribute__((aligned(1024))) X;
  printf("%d\n", (int)&X & 1023);
}
int main() {
  foo();
}

On my machine, this prints "752".
