That solution would be ideal. However it seems that adding CallWith=ScriptState to a function causes the V8 binding generator to invoke the function with an EmptyScriptState rather than with ScriptState::current(). And at the beginning of ScriptValue::serialize(), a ScriptScope is created with this EmptyScriptState. Since the EmptyScriptState has a null v8::Context, the v8::Context::Scope in ScriptScope enters the null context, triggering an assertion failure in V8.
