>Description:
	tst.cc: In static member function `static void T<Y>::f() [with Y = char]':
	tst.cc:21:   instantiated from here
	tst.cc:3: internal compiler error: Segmentation fault

>How-To-Repeat:
	just compile attached source
>Fix:
	
// tst.cc
struct X
{
    ~X() { }
};

template <class Y> struct T
{
public:
    static void f()
    {
        x.~X();
    }

    static X x;
};

int
main()
{
    T<char>::f();

    return 0;
}
