$cat test.f90
program test
real :: foo
contains
    function foo ()
    end function foo
end program test

Gfortran passes it.

If add external attribute, we'll get ICE.

$cat test2.f90
program test
real, external :: foo
contains
    function foo ()
    end function foo
end program test
$gfortran test2.f90
test2.f90: In function ‘MAIN__â€?
test2.f90:7: internal compiler error: in build_function_decl, at fortran/trans
