Symptoms:
	PHCO_18138:
	The restore command core dumps when restoring a dump of a
	file system with a large number of inodes.

	PHCO_14419:
	restore(1m) was unable to read some cross-platform
	dump archives under 10.20 that were readable under
	previous releases.

Defect Description:
	PHCO_18138:
	When restoring a dump of a file system with a very large
	number of inodes, the restore command core dumps while
	attempting to extract the inode map.  The software defect
	begins to be a problem when the maximum number of inodes
	for a file system is approximately 4 million, though it
	does not core dump and may not have any other visible
	adverse affects.  When the maximum number of inodes for a
	file system reaches approximately 8 million, the command
	dumps core.
	Resolution:
	When extracting the inode map, the code was using the
	s_spcl.c_addr[] array when reading in blocks of the map.
	The s_spcl.c_addr[] array has a size of 512.  If the map
	was larger than 512 blocks, restore would write beyond
	s_spcl.c_addr[512].  The new code defines a new "c_addr"
	variable which is dynamically allocated for the map
	extraction.

	PHCO_14419:
	An off-by-one error was introduced, at 10.20,
	into the restore(1m) code which deals with
	quad-swapping.
