Depends on how you define "correctly."

There is no such conversion defined within the language, because the
language would need some way to verify that this address is the
correct place to enter a routine with the given profile.

That's the only way I can imagine.  It is NOT "incorrect", but it IS
extremely compiler-dependent.  If you port to a different platform,
compiler brand, or compiler VERSION, you'll need to re-verify that this
works right.
