  Modified files:
    gnu/usr.bin/tar      diffarch.c 
  Log:
  Quick fix for attempts to free non-malloc()ed memory.  The variables
  current_file_name and current_link_name sometimes point into the
  middle of malloc()ed memory and sometimes point to alloca()ed memory,
  but free() is sometimes called on them.  This seems to be harmless
  for the usual tar operations, but it is usually fatal for `tar -W'.
  E.g., for `cd /etc; tar Wcf /tmp/foo rc', at the start of
  verify_volume(), current_file_name points to alloca()ed memory, and
  tar attempts to free it.
