+// Bug 758509 changed things so that a JSScript is partially initialized when
+// it is created, which is prior to bytecode generation; full initialization
+// only occurs after bytecode generation. This means that
+// JSScript::markChildren() must deal with partially-initialized JSScripts.
+// This test forces that to happen, because each let block allocates a
+// StaticBlockObject. All that should happen is that we don't crash.
