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

=========================================
template<int> struct A
{
    int& i;
    A();
    ~A() { &A::i; }
};

A<0> a;
=========================================

bug.cc: In destructor 'A<<anonymous> >::~A() [with int <anonymous> = 0]':
bug.cc:9:   instantiated from here
bug.cc:6: internal compiler error: in gimplify_expr, at gimplify.c:5763
Please submit a full bug report, [etc.]

Before we got the error message:

bug.cc: In destructor `void A<<anonymous> >::A() [with int <anonymous> = 0]':
bug.cc:9:   instantiated from here
bug.cc:6: cannot create pointer to reference member `A<0>::i'
