[Bug fortran/16228] New: [gfortran] character arrays not initialized properly with data statements

["bdavis at gcc dot gnu dot org" <gcc-bugzilla@gcc.gnu.org>]

character arrays are not padded with blanks, however character variables are.


! demonstrates a character array is initialized
! differently from a character variable
       IMPLICIT NONE
       CHARACTER*2 STR1(3)
       CHARACTER*2 STR2
       DATA STR1 / 'L','L','L' /
       DATA STR2 / 'L' /
       print '(3Z8,5X,Z8)',STR1,STR2
       IF (STR2 .EQ. STR1(1)) THEN
         print*,'they are equal'
       else
         print*,'they are not equal'
       END IF
       END
