There's nothing in the standard that says that.  In fact, when the
compiler sees:

  struct S { }; /* Double sized thing full of shorts */
  new S;

it can give back short-aligned memory, even if `malloc' would normally
give back memory with enough alignment for a double.

Any program making the assumption you state is broken, I think.
