I would rather call it a bug :-)

The truncation warning is a separate thing. For instance, it (correctly)
triggers for the following valid code:

  print *, [character(len=2) :: "ab", "hjf333"]

and it does not trigger for the invalid

  character(len=*), parameter :: str = "123"
  print *, [str, "ab"]
  end

(Obviously also not for the valid "[character(len=20) :: "ab", str]".)
