Hmm, I tried it out and built gcc-9.2.0 out of the release tar ball,
with no checking flag....
and, actually the test case still ICEs, just in a different
place:

$ gfortran -c z1.f90
z1.f90:5:0:

    5 | end

Please submit a full bug report,

Please include the complete backtrace with any bug report.
See <https://gcc.gnu.org/bugs/> for instructions.


And the patch applies cleanly and fixes the issue.

So I guess I will look at running a reg-test cycle
and send the patch to the fortran mailing list when that is
done.
