Description

OpenSuse, the modern github ksh93 project and Solaris have all imported a set of patches to improve stack robustness in ksh93.

This patch addresses an issue with the ksh93 internal stack restoration
and resizing logic which was causing random coredumps, mainly in nested shell scripts.
