Is there a recommended pattern to ensure finalizer functions are invoked when cleaning up the Runtime/Context?

When using the "Class" API in QuickJS (JS_NewClass()), I'm seeing the finalizer function not be invoked when the program is shutting down, which leads to reported memory leaks. I would want these finalizers to be invoked before the JS_FreeContext(ctx); JS_FreeRuntime(rt); calls. Is this the normal behavior of QuickJS or am I doing something wrong?

JS_FreeRuntime() should run any finalizers whose objects have a reference count of 1. Try building quickjs with -DDUMP_LEAKS=1.

Sure, so for example I get something like:

Object leaks:
       ADDRESS REFS SHRF          PROTO      CLASS PROPS
   0xa720d8f80    1   0*            0x0 TlsContext {  }
Memory leak: 1160 bytes lost in 4 blocks

So since REFS is 1, should that not qualify for finalization?

Is that held on another JS object but on the native side by any chance?

Then you'll need to mark it in the mark phase too.
