+    BZ#331380 cont. Don't crash if evp->sigev_notify is invalid. Fix scalar test.
+    
+    We check evp.sigev_notify_thread_id only if evp->sigev_notify has
+    SIGEV_THREAD_ID set. But before checking we need to make sure accessing
+    evp->sigev_notify is valid.
+    
+    Fix memcheck/tests/x86-linux/scalar.stderr.exp output.
+    We now produce separate warnings for the 3 different fields.
