Node-API related segmentation fault

that’s probably a case to not worry about 😆 in standard conforming C/C++ implementations, I guess it is possible to reliably set a function pointer to null.

Node-API related segmentation fault

I created an external with no finalizer callback (nullptr) and - deno just treats it as normal c callback and goes ahead to call it sometime - node will check if its null then its not called

Node-API related segmentation fault

seems that finalizer cb being null is not handled correctly in deno

FFI Difference between buffer and pointer

If you're only passing typed arrays (prefer Uint8Arrays as they can be optimized in Deno FFI), use buffer type. If you're only passing pointers that some other function returns, use the pointer type. Using pointer type + Deno.UnsafePointer.of(TypedArray) it will have some performance overhead due to additional call. Prefer buffer type for passing typed arrays
