            Bug ID: 86469
           Summary: Dwarf Error: Offset (1678049557) greater than or equal
                    to .debug_str size (5846).
           Product: gcc
           Version: 8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jg at jguk dot org
  Target Milestone: ---

Is this a known issue? I saw some other tickets but am not knowledgeable. Or is
it an LD issue?

It's easy enough to reproduce, it is a function which doesn't match the
protottype

void get_err_whois(int wh_res, string & err_str);

void get_err_whois(wh_res_e wh_res, string & err_str)
{
// implementation
}

I don't yet have a small test case.
