I assume you are using the API wrong. This following cctest code worked
perfectly fine for me:
THREADED_TEST(ArraySetLength0) {
v8::HandleScope scope;
LocalContext context;
v8::Handle<v8::Value> value = CompileRun("[1, 2, 3]");
CHECK(value->IsArray());
v8::Handle<v8::Array> array = v8::Handle<v8::Array>::Cast(value);
array->Set(v8_str("length"), v8::Number::New(0));
CHECK_EQ(0, array->Length());
}
