with GCC configured with

../../gcc/configure

To reproduce:

$ cd {build_dir}/gcc && make check RUNTESTFLAGS="dg.exp=g++.dg/cpp2a/decomp10.C 
--target_board='unix{-m32}'"
$ cd {build_dir}/gcc && make check RUNTESTFLAGS="dg.exp=g++.dg/cpp2a/decomp10.C 
--target_board='unix{-m32\ -march=cascadelake}'"
$ cd {build_dir}/gcc && make check RUNTESTFLAGS="dg.exp=g++.dg/cpp2a/decomp10.C 
--target_board='unix{-m64}'"
$ cd {build_dir}/gcc && make check RUNTESTFLAGS="dg.exp=g++.dg/cpp2a/decomp10.C 
--target_board='unix{-m64\ -march=cascadelake}'"

(If you met problems with cascadelake related, disabling AVX512F in command 
line might save that.)
(However, please make sure that there is no potential problems with AVX512.)
