Trying to stuff a value into a signed object that cannot hold that
value results in implementation defined behaviour. You could have
just set off that 3 tons of fertilizer they found in Canada. Only
stuffing into unsigned objects has a defined action.

On a conversion to a signed integer type, if the value cannot be
represented, "either the result is implementation-defined or an
implementation-defined signal is raised". There is no undefined
behavior.

Doesn't the phrase "implementation defined behaviour" mean just
that? To me, that includes signalling or peculiar result values.
