Subject: bash: executes statement after "exit"

Date: Sat, 26 Mar 2016 19:47:59 +0100

Package: bash
Version: 4.3-11+b1
Severity: normal

% cat bash-bug
#!/bin/bash

if true; then
  $[()]
  exit
fi

echo "Should not get here."
% ./bash-bug
./bash-bug: line 4: (): syntax error: operand expected (error token is ")")
Should not get here.

The error is correct, but after that it should continue with exit,
or with "set -e", abort immediately. In both cases it goes on to
execute the statement below.
