I can confirm this behavior with trunk and 6.2.0 20161005 (Ubuntu
6.2.0-5ubuntu12).

This is what I get with 5.4.1 20160929 (Ubuntu 5.4.1-2ubuntu2). Which version
of gfortran 6 are you using exactly?

Note that even earlier versions (4.x) put the '1' right under the 'a', not
under the opening brace.

The warning comes from compare_parameter in interface.c.
