OK, this is as short as I can get it (but that should suffice):
-----------------------------
struct A {
    ~A() throw() { }
};

struct B {
    B(const A& __a) : p(0) { }
    int* p;
};

template<typename> struct V : B {
    V() : B(A()) { }
    ~V() {}
    int & foo();
};

void f() {
  int index = V<int>().foo();
}
------------------------------
mp/gg> ../build-gcc/gcc-install/bin/c++ -c z.cc -fgcse -fnon-call-exceptions -O
z.cc: In function `void f()':
z.cc:18: internal compiler error: in commit_one_edge_insertion, at cfgrtl.c:
   1546
