+
+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'):
