Sure, which is why you have to
(a) know what kinds of unchecked conversions you expect
to be supported
(b) know enough to know what kinds of unchecked conversions
are in fact almost certain to be supported in all
implementations. Remember that vendors are interested
in making your code run, not taking advantage of the
RM to ensure that your code does NOT run :-)
Also note that there is a big difference between an
instantiation of unchecked conversion that is rejected
at compile time, and an address overlay that is accepted,
but causes mysterious runtime failures, perhaps dependent
on subtle optimization effects!
