Bash Version: 2.04
Patch Level: 0
Release Status: release

Description:
        "set -e" does not abort the entire script when used inside a
        parenthesized subshell; it only aborts the subshell.

Repeat-By:
        trap 'echo Congratulations, your shell is not buggy' 0
        set -e
        (false; echo you will not see this)
        trap 0
        echo You have the bash -e bug.
        exit 1

    Output with bash:
        You have the bash -e bug.

    Output with other shells (pdksh, zsh, Solaris /sbin/sh and ksh, AIX sh,
                              bsh, and ksh, DU sh and ksh):
        Congratulations, your shell is not buggy
