--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Created attachment 58960 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=58960&action=edit Preprocessed source Note I removed the body of EndsWithValidator::EndsWithValidator and the include fmt/format.h and ranges since they are not needed to get the ICE.
