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'):
