--- Comment #23 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Created attachment 59266 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=59266&action=edit A different reduced testcase ` -std=c++20 --param ggc-min-expand=0 --param ggc-min-heapsize=0 -O3 -flto` This one requires =0/=0 but I can't reproduce it locally with =0, only =1.
