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