--- Comment #11 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
The testcase fails for me in gcc 11 on both x86_64-linux and i686-linux
(--enable-checking=yes,rtl,extra):
+FAIL: g++.dg/vect/pr109573.cc -std=c++20 (internal compiler error)
+FAIL: g++.dg/vect/pr109573.cc -std=c++20 (test for excess errors)
+FAIL: g++.dg/vect/pr109573.cc -std=c++2b (internal compiler error)
+FAIL: g++.dg/vect/pr109573.cc -std=c++2b (test for excess errors)
