Called automatically upon a bad cast (one that loses precision or attempts
to convert a negative value to an unsigned type). The source type is Src
and the destination type is Dst.
Nominally the result is the desired value of the cast operation,
which will be forwarded as the result of the cast. For Throw, the
function never returns because it throws an exception.
