Fixed In Version: ksh-20120801-10.el6_5.8
Doc Type: Bug Fix
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.
