Well, that's weird.  It appears that I'm the guilty person.
'git blame resolve.cc' leads to 7d92901c878c

    Fortran: Check IMPURE in BLOCK inside DO CONCURRENT.

            PR fortran/117765

    gcc/fortran/ChangeLog:

            * resolve.cc (check_pure_function): Check the stack to
            see if the function is in a nested BLOCK and, if that
            block is inside a DO_CONCURRENT, issue an error.

    gcc/testsuite/ChangeLog:

            * gfortran.dg/impure_fcn_do_concurrent.f90: New test.
