--- Comment #5 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> ---
The issue was fixed by the patch for PR121616 (r16-3809?, Harald
Anlauf, 2025-09-11): "Fortran: fix assignment to allocatable scalar
polymorphic component". gfc_variable_attr gave a scalar CLASS
component of an array element (s(i)%x) the dimension attribute of
the array reference, so s(4)%x = s(1)%x was mis-compiled.
It was backported to all open branches and is in 13.5.0, 14.4.0,
15.3.0 and 16.1.0:
trunk 0899b826f71
gcc-15 9bfc496528d
gcc-14 79cb8847859
gcc-13 98f784357be
Both attached examples (ch28 with ch2806_shape_module.f90, and
ch29) run correctly with 13.4.1, 14.4.1, 15.3.1, 16.2.1 and trunk.
Reverting only the PR121616 change on the gcc-13 branch brings back
the segfault in both. Closing as a duplicate of PR121616.
