--- Comment #7 from urbanjost at comcast dot net --- Did not mean to get a debug session for the code. The code had been working for several years and "broke" when I updated gfortran (and incidently, gcc). Thanks to everyone for looking at it so promptly. Wasted a bunch of time condensing the Fortran down to a simple reproducer, when it was in the C all along.
