[Bug c++/37715] Different class sizes with public/private and alignments

[pinskia at gcc dot gnu dot org]

------- Comment #2 from pinskia at gcc dot gnu dot org  2008-10-03 20:46 -------
In the private case, A is a non-POD so _c can fit tail part of A.  So the
sizeof(M) is 16 bytes.
In the public case, A is a POD so _c is not allowed to be in the tail part of A
(as required by the C++ standard), so the sizeof(M) is 2 * 16.  The sizeof (_c)
is 1 as required by the C++ standard.

For the non aligned case, there is no tail part of A for the non POD case as
the alignment and size are equal.
