Updated expect packages that fix one bug are now available for Red Hat Enterprise Linux 6.
The "expect" packages contains a tool for automating and testing interactive command line programs and Tk applications. Tcl is a portable and widely used scripting language, while Tk is a graphical toolkit that eases development of text-based and GUI applications.
Prior to this update, the "expect" utility leaked memory when used with the "-re" option, and its memory usage kept increasing indefinitely. A patch has been provided to fix this bug, and "expect" memory usage is now stable and without any leaks.
Users of expect are advised to upgrade to these updated packages, which fix this bug.
