Bash Version: 3.1
Patch Level: 17
Release Status: release

Description:
    If you have an assignment with a wrong expression, e.g. VAR=$[8#9] bash
    displays an error message and the script runs on. But if this error
    is inside a for loop - or two nested for loops - bash leaves all loops
    at once and goes to the next statement after all loops. I would expect
    bash to continue with the next statement in the loop. Or at least abandon
    the script. I do not have a problem with the error itself but with the
    handling of it in the bash.

Repeat-By:
        #!/bin/bash
        echo "Start"
        von=$[8#9]
        echo "vor verschachtelter Schleife"
        for j in 1 2; do
            echo "Start outer $i"
            for i in 1 2; do
                    echo "Start inner $i"
                    vom=$[8#9]
                    echo "OK inner $i"
            done
            echo "RC inner for: $?"
            echo "OK outer $j"
        done
        echo "RC outer for: $?"
        echo "vor einfacher Schleife"
        for i in 1 2; do
                echo "single $i"
                von=$[8#9]
                echo "OK single $i"
        done
        echo "RC single for: $?"
        echo "Ende"
