      Description

      Java SEGV's in InetAddress.getByName (probably in lookupHostAddr()).

      System is Sparc 4 running Solaris 2.4 11/94 release.

      My shell is ksh (this causes some problems where my $ENV contents turn
      on things like noclobber - how about using the -p flag on the #! line to
      disable $ENV parsing?)

      Same error happens if I login as 'root' and run standard Openwin with
      no special environment config.
