[GBA] mGBA Pokemon Gold overworker crash on exit about cloud-game HOT 9 CLOSED

It's just mGBA not ported properly for Libretro API, more precise their custom mem deallocator.
I have nothing against Libretro, speaking of GO/CGO I meant that it's not quite on the level of performance and dev-friendliness with other FFI providing languages like Rust or Crystal. Not sure about screen capture or Wayland like display client/servers but yeah, I'm pretty sure that the first we should describe the worker as a high-level interface for coordinator and user-agent, then one can write it whatever way he wants: Libretro-nanoarch-like, bare metal os, or screen-capture, and so on.

Thank you for reporting that. I will take a look at it :D

It indeed crashes with ludo also. Seem like problem with libretro. Will try to work around and recover from libretro error.

it's problem with libretro, it crashed with retroarch as well. I think it's libretro limitation. I think I will just remove this game.

Retroarch can unload this game with mGBA. I will try to look at their code, maybe there is something interesting and will read about handling unexpected app terminations in C but handle it from CGO is quite a challenge and possible is impossible. (:
(the more I look at CGO the more I begin to think that using it for libretro bridge is a mistake)

Maybe the Libretro ported in CGO has problem. I remember I got issue with https://github.com/libretro/ludo, https://github.com/libretro/go-nanoarch
And I'm having plan to move away libretro, so we have more flexibility. Running a game entity separately and capture the screen is enough. Communication between the game and the app uses Inter-Process Communication. Do you think it should be the way to go?

This is mGBA problem with the Libretro API. During core unload call they are dereferencing a null pointer. Must be fixed on their side. No idea how to handle this through CGO.
