The node REPL seems to crash if a C++ getter creates an instance of a class that extends ObjectWrap.
This works in a script, but it crashes as soon as the REPL's auto-complete attempts to "preview" bar.get_new_foo:
#include <napi.h>
struct Foo : public Napi::ObjectWrap<Foo> {
static Napi::Function Init(Napi::Env env, Napi::Object exports) {
return DefineClass(env, "Foo", {});
}
Foo(Napi::CallbackInfo const& info) : Napi::ObjectWrap<Foo>(info){};
};
struct Bar : public Napi::ObjectWrap<Bar> {
static Napi::Function Init(Napi::Env env, Napi::Object exports) {
FooConstructor = Napi::Persistent(Foo::Init(env, exports));
FooConstructor.SuppressDestruct();
return DefineClass(env, "Bar", {InstanceAccessor<&Bar::get_new_foo>("get_new_foo")});
}
Bar(Napi::CallbackInfo const& info) : Napi::ObjectWrap<Bar>(info){};
private:
static Napi::FunctionReference FooConstructor;
Napi::Value get_new_foo(Napi::CallbackInfo const& info) {
