[Crash-utility] Problem with "xm save" x86-64 cores - crash.4.0-3.5

Crash exits with an error "cannot determine pid_hash array dimensions". Looking at the crash change log, it appears that it was fixed in 4.0-2.24 for the 2.6.17 kernel. The core I have is of a 2.6.16.13 xenified kernel. Is the fix even relevant ? <output> $ ./crash vmlinux-2.6.16.13-xen test.core crash 4.0-3.5 Copyright (C) 2002, 2003, 2004, 2005, 2006 Red Hat, Inc.

(gathering task table data) crash: cannot determine pid_hash array dimensions </output> Is there a way I can get crash's source at releases 4.0-2.24 and 4.0-2.23 so that I can try a fix for this kernel in case it is a specific kernel fix ?
