--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
It's not clear that only Fortran is affected but GCC 11 rejected the code with
t.f90:3:15:
3 | !$omp task affinity (iterator(j=1:8) : a(j))
| 1
Error: Failed to match clause at (1)
t.f90:4:17:
4 | !$omp end task
| 1
Error: Unexpected !$OMP END TASK statement at (1)
so it's not a regression.

This is the same problem as PR103695, or at least it's fixed by the same patch.

Fortran: Fix scope for OMP AFFINITY clause iterator variables [PR103695]
gfc_finish_var_decl was confused by the undocumented overloading of
the proc_name field in struct gfc_namespace to contain iterator
variables for the OpenMP AFFINITY clause, causing it to insert the
decls in the wrong scope. This patch adds a new distinct field to
hold these variables.
