--- Comment #1 from Aldy Hernandez <aldyh at gcc dot gnu.org> ---
I cannot confirm, as I don't have access to spec, but this looks very simil=
ar
to PR96818 which I can reproduce.  It's not the exact same pathway, but they
both end up calling find_case_label_range() which I have definitely touched
with my patch.

I will mark this as depending on 96818 for now, and perhaps the reporter can
monitor that PR for proposed fixes.

Thanks for reporting this.
