I think approach of not killing group leader is incorrect, it should also be killed. Your patch works because linux_exit_group is called for the second time when only group leader is available. Such behavior is not expected, control should not return to userspace from linux_exit_group. I've submitted another PR, it contains fixes for 2 linux exec bugs. I've followed NetBSD and patched exit1() to allow process exit status to be changed by event handlers. Would appreciate if you could test the patch: http://www.freebsd.org/cgi/query-pr.cgi?pr=144194 Thanks, Gleb
