[Bug c++/30975] ptr to member func __delta is 0 if ptr declaration does not match function porototype

What exactly are you trying to achieve here:
-------------
typedef void (B::*FPTR)(int);

...

struct C : public A , public B {
    virtual void C_bad() { }
};


  c.t((FPTR)&C::C_bad);
------------------
Clearly, C::Cbad is a void function, but you assign it to a pointer to a
function that takes an int. That can't possibly work. Indeed, if you let
C_bad take an int, the segfault goes away.
