            Bug ID: 98558
           Summary: Scalar character parameter does not print warning if
                    actual length >1
           Product: gcc
           Version: 9.2.0

          Severity: normal
          Priority: P3

test program

More of a suggestion than a bug (I don't see memory issues).

If I initialize a CHARACTER, PARAMETER variable with a string whose lenght is
>1, no warnings are printed in gcc/gfortran 9.2.0: 

program test_char_parameter
      implicit none
      character       , parameter :: a = 'a'      ! OK
      character       , parameter :: b = 'bbbbb'  ! NO -> No warnings printed!
      character(len=1), parameter :: c = 'ccccc'  ! NO -> No warnings printed!
      character(len=*), parameter :: d = 'ddddd'  ! OK

      print *, a
      print *, b
      print *, c
      print *, d

end program test_char_parameter

Best,
Federico
