To reproduce:
$ cd {build_dir}/gcc && make check RUNTESTFLAGS="dg.exp=gfortran.dg/associate_91.f90
--target_board='unix{-m32}'"
$ cd {build_dir}/gcc && make check RUNTESTFLAGS="dg.exp=gfortran.dg/associate_91.f90
--target_board='unix{-m32\ -march=cascadelake}'"
(Please directly reply to this email for question about this report.)
(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.)
I am able to reproduce this here so I am working on it now.
Thanks for info.
Jerry
