I finally took the time to see why unzip (available from simtel20.arpa
in pd2:<misc.unix>) core dumped under AIX 2.2.1/RT. It seems that the
two realloc calls for the comment tags would cause a segmentation
fault if handed a size field of zero on some occasions. You can
probably solve this with an if statement but I just changed it to
realloc the requested size plus 1 (what's an extra byte among
friends). Anyways, all is right with the world once again.
