The following (valid ?) code snippet triggers an ICE since GCC 4.2.0:
=========================================
struct A
{
char c;
int& i;
};
int j = __builtin_offsetof (A, i);
=========================================
bug.cc:7: warning: invalid access to non-static data member 'A::i' of NULL
object
bug.cc:7: warning: (perhaps the 'offsetof' macro was used incorrectly)
bug.cc:7: internal compiler error: in fold_offsetof_1, at c-common.c:6838
Please submit a full bug report, [etc.]

------- Comment #2 from jakub at gcc dot gnu dot org 2008-04-02 17:17 -------
IMNSHO this is invalid.
[lib.support.types]/5 says the first argument must be a POD structure or POD
union, but struct A isn't POD structure because of the reference in it.
