--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed.

>but not on 13.2 with -std=3Dc2x
Yes it does just hidden from the user really:
<source>:3: confused by earlier errors, bailing out

is an ICE after an error with --enable-checking=3Drelease (which is the def=
ault
for release branches).

Anyways 12.x didn't ICE for the one in comment #1.=
