BASH PATCH REPORT
=================
Bash-Release: 4.4
Patch-ID: bash44-008
Bug-Reported-by: Koichi MURASE <myoga.murase@gmail.com>
Bug-Reference-ID: <CAFLRLk-V+1AeQ2k=pY7ih6V+MfQ_w8EF3YWL2E+wmLfgKBtzXA@mail.gmail.com>
Bug-Reference-URL: http://lists.gnu.org/archive/html/bug-bash/2016-11/msg00050.html
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.
Patch (apply with `patch -p0'):
