## This tests dumping a .debug_str_offsets.dwo section in a DWP file when it is
## referenced by units in different formats: one unit is DWARF32 and another
## is DWARF64, thus the .debug_str_offsets.dwo section has contributions with
## different sizes of offsets.
## This also checks that attributes in the units which use the DW_FORM_strx form
## are dumped correctly.
