4.7. bash

Updated bash packages that fix one bug are now available for Red Hat Enterprise Linux 5.
The GNU Bourne Again shell (Bash) is a shell and command language interpreter compatible with the Bourne shell (sh). Bash is the default shell for Red Hat Enterprise Linux.

Bug Fix

When a trap handler was invoked while running another trap handler, which was invoked during a pipeline call, bash was unresponsive. With this update, pipeline calls are saved and subsequently restored in this scenario, and bash responds normally.
Users of bash are advised to upgrade to these updated packages, which fix this bug.
