From my quick investigation the problem seems to be that gfortran uses a DW_FORM_string for the compile unit's name (rather than a DW_FORM_strp)

              DW_AT_name [DW_FORM_string]       ("/nfs/homes/jdelsign/hello.c")

and ld might have an off-by-one error when decoding the FORM (that part is speculation on my end based on that dwarfdump can decode the string fine, but it could also be a bug in gfortran and dwarfdump skips the control character when printing).
