[Bug c++/16810] New: Legal (?) C++ program with cast gives ICE in build_ptrmemfunc

["sje at cup dot hp dot com" <gcc-bugzilla at gcc dot gnu dot org>]

The following C++ program will not compile with g++ versions 3.4.1 or 3.5,
I tried the ia64-hp-hpux11.22 platform as well as hppa-hp-hpux11.00.


struct C {
    virtual void f() {}
};

struct B {virtual ~B() {} };

class D : public B, public C
{
public:
    virtual void f() {}
};

typedef void ( C::*FP)();
typedef void ( D::*D_f)();

int main() {
  D *d = new D();
  C *c = d;

  const FP fptr = (FP) &D::f;;
  (d->* (D_f)fptr)();
}

-----------------------------------

/usr/local/bin/g++ -c x.C
x.C: In function `int main()':
x.C:21: internal compiler error: in build_ptrmemfunc, at cp/typeck.c:5512
