[Bug fortran/20895] New: error needed

[jv244 at cam dot ac dot uk]

The following is non-standard and the compiler should probably generate a
warning/error with '-pedantic -std=f95'

  CHARACTER(LEN=10), TARGET :: a
  CHARACTER(LEN=4), POINTER :: b
  b=>a
  END

I don't think so, I'm sure this code is valid, but I believe you know the
standard well enough to justify your statement.

Well, don't know the standard reference, but the Sun compiler does error out on
this code.

I am going to go out on a limb and say this is invalid so confirmed.

Length is a type parameter.  All type parameters shall be identical in a POINTER
assignment. Hence the example is illegal.

This means that bound checking should reject the following for i /= 5:
  character*5, pointer :: p
  character*10, target :: t

  p => t(1:i)
