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:

Readline-7.0 changed the way the history list is initially allocated to reduce
the number of reallocations and copies.  Users who set the readline
history-size variable to a very large number to essentially unlimit the size
of the history list will get memory allocation errors 

Patch (apply with `patch -p0'):
