So:

  if (find_pc_partial_function (pc, NULL, &func_addr, &func_end))
    {
      sal = find_pc_line (func_addr, 0);
      if ((sal.line != 0) && (sal.end < func_end))
        return sal.end;
    }

find_pc_partial_function and find_pc_line succeed, but sal.end=func_end,
right? This is the problem I had. Line table problems from gcc was my
determination.

The prologues I was looking were exactly like this. I think we may be
seeing the same problem. What does readelf say for the line info?
