-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

-Bug-Description:
-
-Under certain circumstances, bash will evaluate arithmetic expressions as
-part of reading an expression token even when evaluation is suppressed. This
-happens while evaluating a conditional expression and skipping over the
-failed branch of the expression.
-

-signal arriving between the time the history length is updated and the time
-the history list update is completed. A later attempt to reference an
-invalid history entry can cause a crash.
