--- Comment #1 from Robert Dubner <rdubner at gcc dot gnu.org> ---
This is a case where I am not sure what to do.

When I compile and run the reproducer using gcobol-17 (built from the gcc
master development branch) the results are as expected.

I have not as yet ever done a bug fix to an already-released version of GCC.

This is also relevant to Peeter Joot's reported PR125616, which I have reported
as RESOLVED/FIXED.  But I fixed it only in -17.

So I could use some advice about where to go from here.
