--- Comment #3 from Tom de Vries <vries at gcc dot gnu.org> ---
As mentioned before, this failure shows up with gcc 9.4.0.

It doesn't show up with gcc 12.2.1, because of a difference in generated co=
de.

In the 12.2.1 case we have 4 insns:
...
  401208:       8b 55 cc                mov    -0x34(%rbp),%edx
  40120b:       8b 45 d0                mov    -0x30(%rbp),%eax
  40120e:       29 c2                   sub    %eax,%edx
  401210:       89 55 d4                mov    %edx,-0x2c(%rbp)
...
each with their line number entry:
...=20
step-reverse.c         78            0x401208               x
step-reverse.c         78            0x40120b               x
step-reverse.c         78            0x40120e               x
step-reverse.c         78            0x401210               x
...
