[Bug fortran/39791] New: Bad Dwarf debug information from gfortran for a character string.

["david dot sagan at gmail dot com" <gcc-bugzilla@gcc.gnu.org>]

A simple example shows the problem:

program test
  implicit none
  integer i
  character(16) abc
  abc = "abc"
  i = 7
end program

Compile with:
  gfortran -g -O0 test.f90

Run with gdb and "whatis abc" produces:
  type = character(kind=1) (16)

That is, gdb thinks that the variable abc is an array of length 16 with each
component in the array being a singe character. I verified with the totalview
debugger that the problem was with the compiler and not gdb. Interestingly
enough, version 4.1.1 does *not* have this problem. This bug definitely makes
debugging a program more painful.
