+Summary: Incorrect dead code optimization
+
+Consider the test:
+using System;
+class Test {
+  static void Main() {
+     test1(true, 50);
+  }
+  unsafe static void test1(bool val, int o) {
+    int vInt = 111;
+    test3((long)(&vInt));
+  }
+  unsafe static void test3(long i) {
+    Console.WriteLine("Address of local is: 0x{0:x} ({1})", i, *(int*)i);
+  }
+}
+
+It should print 111 but doesn't because recent changes in the jit will
+remove the = 111 assignment as dead.
