--- Comment #9 from Gerhard Steinmetz <gerhard.steinmetz.fort...@t-online.de>

Frankly speaking, it's difficile. Smells more invalid than valid.
As a side note, I do not have any production code using a contruct
similar to that in comment 0 or in recursive_interface_*.
Still affects some examples from testsuite/gfortran.dg :
- data_value_1.f90
- recursive_interface_1.f90
- recursive_interface_2.f90
$ gfortran-7-20161204 -c recursive_interface_1.f90
$ gfortran-7-20161204 -fimplicit-none -c recursive_interface_1.f90
recursive_interface_1.f90:16:0:
