System: Sun-3/280, SunOS 3.4.

The command line:

    gnutar -c -b 100 -v -f /tmp/rmt0 -z -l -V "cps45x: /usr 1-16-88" \
    -X /usr/users/staff/rang/stuff/00yy .

causes GNU tar to crash with the message "Couldn't re-allocate memory". 
I tracked it down to the routine add_exclude in tar.c, which calls
ck_realloc() on a null pointer.
