             Bug #: 15030
           Summary: do_lookup_x returns undefined symbol entry
           Product: glibc
           Version: 2.18
            Status: NEW
          Severity: normal
          Priority: P2
         Component: dynamic-link
        AssignedTo: unassigned@sourceware.org
        ReportedBy: hjl.tools@gmail.com
    Classification: Unclassified


do_lookup_x has

          /* Use the old SysV-style hash table.  Search the appropriate
             hash bucket in this object's symbol table for a definition
             for the same symbol name.  */
          for (symidx = map->l_buckets[*old_hash % map->l_nbuckets];
               symidx != STN_UNDEF;
               symidx = map->l_chain[symidx])
            {
              sym = check_match (&symtab[symidx]);
              if (sym != NULL)
                goto found_it;
            }


When the old SysV-style hash table, we may return undefined
symbol entry.  We don't run into this problem often since
GNU-style hash table is enabled by most GCC.
