[Bug ld/6924] New: ld does not understand DWARF version 3 when trying to get a source line number

[geir at cray dot com]

Using ld version 2.18 when linking a PGI 7.2-5 compiled program, I see the
following dwarf error:

$ cat datatypes.module.f90
module datatypes
  integer, parameter :: short = 1
end module datatypes
$ cat main.f90
program TEST
  use datatypes
end program TEST
$ pgf90 -Mdwarf3 -g -c datatypes.module.f90                   <
$ pgf90 -Mdwarf3 -g -c main.f90
$ pgf90 -Mdwarf3 main.o
/usr/bin/ld: Dwarf Error: found dwarf version '3', this reader only handles
version 2 information.
main.o:(.debug_info+0x74): undefined reference to `..Dm_datatypes'
$

The "undefined reference" error is a PGI compiler error, so that can be ignored.

The message: "Dwarf Error: found dwarf version '3', this reader only handles
version 2 information." is occurring when the loader is trying to get the line
number for the "undefined reference" error.  'ld' should at least be able to get
the source line number for a code in Dwarf 3 format.
