// Tests that calling napi_remove_wrap and napi_delete_reference consecutively
// doesn't crash the process.
// This is analogous to the test https://github.com/nodejs/node-addon-api/blob/main/test/objectwrap_constructor_exception.cc.
// In which the Napi::ObjectWrap<> is being destructed immediately after napi_wrap.
// As Napi::ObjectWrap<> is a subclass of Napi::Reference<>, napi_remove_wrap
// in the destructor of Napi::ObjectWrap<> is called before napi_delete_reference
// in the destructor of Napi::Reference<>.
