			     BASH PATCH REPORT
			     =================

Bash-Release:	4.4
Patch-ID:	bash44-001

Bug-Reported-by:	Sean Zha <freeman_cha@hotmail.com>
Bug-Reference-ID:	<BN3PR01MB13657D9303EB94BF6E54216E8CCA0@BN3PR01MB1365.prod.exchangelabs.com>
Bug-Reference-URL:	http://lists.gnu.org/archive/html/bug-bash/2016-09/msg00107.html

Bug-Description:

Bash-4.4 changed the way the history list is initially allocated to reduce
the number of reallocations and copies.  Users who set HISTSIZE to a very
large number to essentially unlimit the size of the history list will get
memory allocation errors 

Patch (apply with `patch -p0'):
