--- Comment #8 from Mikael Pettersson <mikpelinux at gmail dot com> ---
I can't reproduce the wrong code using either the fortran test case in #c2 or
the C one in #c3 with gcc-9.4.0 on Kaby Lake R. If I revert the PR92420 fix
both test cases do reproduce the wrong code. Thus I think this was fixed by
PR92420 in gcc-8.4.0 and gcc-9.3.0.
