File fix_shared_memory_cleanup.patch of Package sblim-sfcb.18998
bugzilla#1161745 During exit, the shared memory is marked for deletion and subsequently deleted. This happens in a different thread started by a signal handler that shuts down the entire daemon. Unfortunately, the main loop is not stopped but is waiting on recvmsg which will be EINTR. The other thread then checks if it should trace the error message or not and the trace variable is allocated on the now detached shared memory segment which segfaults. What we should do instead and simply mark the segment for deletion while retaining the attached state. The kernel will clean this up on exit and shmem segment will be deleted while we can avoid invalid pointer dereference. See Bugzilla for details.
