[Bug c++/38699] New: [4.2/4.3/4.4 regression] ICE using offsetof with array

[reichelt at gcc dot gnu dot org]

The following valid code snippet triggers an ICE since GCC 4.2.0:

======================================
struct A
{
  const char* p;
};

void foo()
{
  __builtin_offsetof(struct A, p[0]);
}
======================================

bug.cc: In function 'void foo()':
bug.cc:8: internal compiler error: in fold_offsetof_1, at c-common.c:7647
Please submit a full bug report, [etc.]

The code is accepted by the C frontend.
