! { dg-do compile }

|
! Tests the patch for PR27613, in which directly recursive, scalar
|
|
! functions were generating an "unclassifiable statement" error
|
|
! for the recursive statement(s). This was subsequently determined
|
|
! to be wrong code and the error on 'bad_stuff' was removed.
|
|
! See 12.5.2.1 of the standard and PR30876.
|
|
!
|
|
! Based on PR testcase by Nicolas Bock <nicolasbock@gmail.com>
