error means there is something wrong with the user's source code, and
should generally be associated with the location of an erroneous source
code construct. I don't see how it can be appropriate here; my impression
is that this code should never fail for any compiler input, valid or
invalid, and so an ICE seems better than sorry (which is for some
well-defined source code feature lacking GCC support, or exceeding
implementation limits in GCC).
