            Bug ID: 28931
           Summary: hosts lookup broken for SUCCESS=CONTINUE and
                    SUCCESS=MERGE
           Product: glibc
           Version: 2.35
            Status: NEW
          Severity: normal
          Priority: P2
         Component: libc
          Assignee: unassigned at sourceware dot org
          Reporter: siddhesh at sourceware dot org

  Target Milestone: ---

SUCCESS=CONTINUE should discard any results so far and try the next NSS module.
 The current implementation in gaih_inet however does not do that. 
SUCCESS=MERGE should merge results from the previous and next module but that
is broken with gethostbyname4_r, since it tries to allocate both into the same
scratch buffer, overwriting the previous results.
