I would expect that the error is referencing a DIE at an offset of 0x1d1b8 in the .debug_info (or possibly .debug_types) section. I suspect that you will find that this DIE has an attribute which has a reference which points at offset 0x0 which has caused this error message. [ This is the DWARF equivalent of attempting to dereference a NULL pointer :-) ] Of course the real question will then be why is there a reference to 0x0 rather than to an actual DIE.
