[Bug tree-optimization/30252] [4.2/4.3 regression] miscompilation of sigc++-2.0 based code with -fstrict-aliasing

Hmm,
        typedef typed_slot_rep<T_functor> typed_slot;
        typed_slot *typed_rep = static_cast<typed_slot*>(rep);
        return (typed_rep->functor_)();

This code could violate C++ aliasing rules.
