I agree, fixed.

"index 0 out of range of range list table (with range list base 0xXXX) with offset entry count of XX (valid indexes 0-(XX-1))" Maybe that's too verbose/not worth worrying about since this'll only be relevant to DWARF producers trying to debug their DWARFv5, maybe no one will ever see this message in practice. Just a thought.
I have written it to my TODO list as it is orthogonal to this patch.
