177-216: 🩺 Stability & Availability | 🔴 Critical | ⚡ Quick winRoot the prototype address inside
prototype_property_value_with_guard.
proto_addrarrives as a bareusizeand is dereferenced at Line 213 and Line 227. The scope roots onlykeyandreceiver_addr. Between entry and the first use,crate::value::nanbox_string_key(key)allocates, so a moving collection can relocate the prototype object and leaveproto_addrstale.The new Error-family caller makes this reachable:
builtin_prototype_value(prototype_name)resolves a lazy builtin, and the resulting address is passed in raw.array_prototype_property_valuein this same file already roots its prototype (proto_h) for the same reason.Add a third handle and read the prototype back at its point of use.
🔒️ Proposed fix
let scope = crate::gc::RuntimeHandleScope::new(); + let proto_h = scope.root_nanbox_f64(crate::value::js_nanbox_pointer(proto_addr as i64)); let key_h = scope.root_nanbox_f64(crate::value::nanbox_string_key(key)); let receiver_h = scope.root_nanbox_f64(crate::value::js_nanbox_pointer(receiver_addr as i64)); @@ - let proto_ptr = proto_addr as *mut ObjectHeader; - if proto_ptr as usize == receiver_addr() { + let proto_ptr = + || crate::value::js_nanbox_get_pointer(proto_h.get_nanbox_f64()) as *mut ObjectHeader; + if proto_ptr() as usize == receiver_addr() { return None; }Then use
proto_ptr()at thejs_object_get_field_by_namecall.This follows the guideline "A GC-managed value's root store must dominate every subsequent site that can collect", and the learning that raw pointer/
usizelocals are neither GC roots nor pins.🤖 Prompt for AI Agents

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Return the receiver through object_handle, not the stale object local.
object is captured at Line 9 and is a raw local. Before this branch runs, two GC-capable calls execute: js_object_get_own_field_or_undef at Line 465 and call_primitive_closure_value at Line 467, which can run a user valueOf. A moving collection there relocates a pointer-bearing receiver.
!jsval.is_pointer() is true for heap strings and BigInts, which carry a heap address in their payload. For "x".valueOf() or (5n).valueOf(), the branch then returns a stale address. The hasOwnProperty and propertyIsEnumerable arms in this same function already re-read the receiver through object_handle for this exact reason (#6935 / #6943).
The tag view itself is stable, so jsval.is_pointer() stays correct; only the returned payload needs the refresh.
🔒️ Proposed fix
if !jsval.is_pointer() {
- return Some(object);
+ return Some(object_handle.get_nanbox_f64());
}
- return Some(js_object_default_value_of(object));
+ return Some(js_object_default_value_of(object_handle.get_nanbox_f64()));This follows the guideline "A GC-managed value's root store must dominate every subsequent site that can collect".
