[Bug fortran/31818] New: Wrongly accepts namelists with assumed-sized arrays

[burnus at gcc dot gnu dot org]

subroutine test(cha)
  implicit none
  character(len=10) :: cha(:)
  namelist /z/  cha
end subroutine test

This is invalid:
"5.4 NAMELIST statement"
"C574 (R553) A namelist-group-object shall not be an assumed-size array."

Other compilers reject this:

ifort:  A NAMELIST group object must not be an array with nonconstant bounds.
[CHA]
g95:  Variable 'cha' at (1) must have an explicit shape to be in a NAMELIST
NAG f95: Namelist-group-object CHA is an array dummy with non-constant bounds
