The following invalid code snippet triggers an ICE since GCC 4.0.0:

=========================================
struct A
{
  A operator[] (int);
};

struct B
{
  A a;
};

void foo()
{
  __builtin_offsetof(B, a[0]);
}
=========================================

bug.cc: In function 'void foo()':
bug.cc:13: internal compiler error: in fold_offsetof_1, at c-common.c:6850
Please submit a full bug report, [etc.]

Before, the code was rejected as __builtin_offsetof was not yet supported.

The problem is related to PR28573.
