From 2633f0e57b1127f4060d70bf460140dc9bb19386 Mon Sep 17 00:00:00 2001 From: Steve VanDeBogart Date: Tue, 26 Aug 2008 15:14:36 -0700 Subject: exit signals: use of uninitialized field notify_count task->signal->notify_count is only initialized if task->signal->group_exit_task is not NULL. Reorder a conditional so that uninitialised memory is not used. Found by Valgrind.
