[Bug fortran/43136] New: Excess copy-in/copy-out with character argument

[pault at gcc dot gnu dot org]

After fixing, 43072 and friends, one excess copy-in and copy-out remains, where
a substring describes the declared string length.  The testcase is in
internal_pack_9.f90:

subroutine foo2
  implicit none
  external foo
  character(len=20) :: str(2) = '1234567890'
  call foo(str(:)(1:20)) ! This is still not fixed.
end
