For a reference type RT&:

const volatile char* r; // as a data member

// to call the function and capture the return
// add max cv-qualification to avoid having to know it
r=&reinterpret_cast<const volatile char&>(f());

// to return the value
// cast back to an appropriate type with max cv-qualification
// then return to original cv-qualification
return const_cast<RT&>(reinterpret_cast<const volatile RT&>(*r));
