The ICE is due to -Wunused-labels. We try to issue a warning about the label
(already marked as an error because it contains a non-numeric character) being
unused, but said label has no locus (because the parser errored out before
assigning it.
Steve, I'm adding you in the CC list since you were the one who rewrote that
codepath a few months ago, IIRC.
I propose we strengthen the errorn in that case and also for the "Too many
digits" and "Zero is not a valid label", by the following patch:
