The following invalid code snippet triggers an ICE since at GCC 4.0.0:
============================================
struct A
{
static int foo();
};
int i = __builtin_offsetof(A, foo[0]);
============================================
bug.cc:6: error: pointer to a function used in arithmetic
bug.cc:6: internal compiler error: tree check: expected class 'expression',
have 'declaration' (function_decl) in finish_offsetof, at cp/semantics.c:2895
Please submit a full bug report, [etc.]
Testing a patch.
