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.]
