    - update to 0.6.0:
      Fixes for Denial Of Service (possible libdwarf crash):
      * The dealloc required for dwarf_offset_list() was incorrect,
        possibly leading to a crash.
      * The function prototype for dwarf_dietype_offset() changed so
        it can work correctly on DWARF4 objects.
      * A memory leak from dwarf_load_loclists() has been fixed.
      * The function dwarf_get_pubtypes() changed, Dwarf_Type no longer
        exists, correcting a library design mistake made in 1993.
        The function applied to DWARF3 and DWARF4 objects.
      * The set of functions using Dwarf_Type are gone, use Dwarf_Global
        instead.  An object with DW_FORM_strx3 (DWARF5) could result in
        the library either crashing or returning an inappropriate error.
        DW_FORM_strx3 is now handled
