| Doc Text: |
Prior to this update, the compiler optimization dropped parts from the ksh job locking mechanism from the binary code. As a consequence, ksh could terminate unexpectedly with a segmentation fault after it received the SIGCHLD signal. This update implements a fix to ensure the compiler does not drop parts of the ksh mechanism and the crash no longer occurs.
