Description:
        The errexit option does not work, if an error occures in a declare 
statement.

Repeat-By:
        The following code prints "a". The second false terminates the script
but the first does not.
        set -e
        declare a="a"$(false)
        echo $a
        b="b"$(false)
        echo $b
