The following program should occur an error since the same named
entity from different modules cannot be referenced.
However, I compiled successfully, and got output "foo".

I think it is wrong behavior.

module m_foo
contains
  subroutine foo
    print *, "foo"
  end subroutine
end module

module m_bar
  interface foo
    module procedure bar
  end interface
contains
  subroutine bar
    print *, "bar"
  end subroutine
end module

use m_foo
use m_bar

call foo
end
