           Summary: make xtree dump files world wide readable, similar to
                    log files
           Product: valgrind
           Version: 3.14 SVN
          Platform: Compiled Sources
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
  Target Milestone: ---

There is no reason why xtree dump files should not be world wide readable,
similar to log files.
Users can always set the corresponding umask to tighten the permissions.
