[svn-r2689] Purpose:
Bug fix.
Description:
Previously, it has been possible to dereference deleted objects in a file.
Obviously, this is incorrect and could cause all sorts of problems if the
object being dereferenced had been partially over-written with other
information. - This is documented in Bug #493.
Solution:
Check the link count for objects being dereferenced and don't allow any
objects with link counts of zero to be dereferenced.
This fixes bug #493.
Platforms tested:
FreeBSD 4.1.1 (hawkwind)
