But I suspect this is corrupt DWARF, binutils readelf doe= sn't like it: readelf: ./libxul.so.debug: Warning: Bogus end-of-siblings marker detected = at offset 4ac96a6a in .debug_info section readelf: ./libxul.so.debug: Warning: Bogus end-of-siblings marker detected = at offset 4ac96a6b in .debug_info section readelf: ./libxul.so.debug: Warning: Bogus end-of-siblings marker detected = at offset 4ac96a6c in .debug_info section Which is suspiciously close to to the identified DIE. --=20 You are receiving this mail because: You are on the CC list for the bug.=
