             Bug #: 15473
           Summary: null pointer handling in strcmp
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: libc
        AssignedTo: unassigned@sourceware.org
        ReportedBy: htpcucxo@yahoo.co.jp

    Classification: Unclassified


When we use strcmp(p, NULL) with Unix machine, It returns zero.
  But on Linux(glibc) it results into crash.

  I know in this case, the behavior of strcmp is "undefined".
  So it's not bug, but since it's useful for the user to port to Linux 
  from other Unix, it would be nice to select the option etc.
