Engine crash after freeing a player scene in a multiplayer game - suspecting AudioStreamPlayer3D #52853

Godot version

System information

Manajro Linux KDE

Issue description

The engine crash occurs in a multiplayer game when a players scene is being freed.
The crash seems to be related to the AudioPlayer3D node (judging by the backtraces it produces), but also does not occur if there are not peers connected (single-player game).

We have a suspiction that there may be some issue with audio listeners (camera) and audio playback.
Each Player scene in this game contains a FPP camera, so freeing that scenes removes a camera node from the node tree. However in a single player game, there's still a camera being freed and it does not cause a crash...

The game map itself has also a "lobby" camera that's a fallback when no other cameras are present in the scene tree.

Someone reported a crash in Rocket.Chat related to 3D audio listeners not being present in a scene with an AudioStreamPlayer3D, I bet that might be related to this. I haven't had a chance to look into it yet though.

in normal build I don't have such error, so it is possible that this invalid operation corrupt memory, and later entire app crash in different place
also at start I have this errors

That's probably not a memory corruption given that it's just a read operation, but it should definitely be fixed too.

qarmin · 2021-09-29T16:46:14Z

Looks that here camera is null

godot/scene/3d/audio_stream_player_3d.cpp

Lines 385 to 387 in 43cc6dd

    
           for (Camera3D *camera : cameras) { 
        
           	Viewport *vp = camera->get_viewport(); 
        
           	if (!vp->is_audio_listener_3d()) {

I got this crash, but for now I don't have reproduction steps

Oh gosh I forgot I never fixed this. Expect a fix this weekend. If I forget again you can break down my front door and demand one. :)

To be clear that was a joke pls don't break down my door everyone ❤️

jitspoe · 2021-11-18T00:45:15Z

While attempting to reproduce the random pitch crash in master, I ran into this crash when closing the program. Basically, the camera is set to null, and the callback to update the listener tries to use the null camera.

 	godot.windows.opt.tools.64.exe!main(int argc, char * * argv) Line 199	C++

In AudioStreamPlayer3D::_update_panning():

	for (Camera3D *camera : cameras) {
		Viewport *vp = camera->get_viewport();
		if (!vp->is_audio_listener_3d()) {
			continue;
		}

camera is null here, as it has just been cleared.

So maybe my players dying thing was also caused by the current camera being freed?
Maybe if I explicitly switched camera before freeing the scene it would not crash?

Yeah, looks like the call stack is the same after _propagate_exit_tree, so removing a camera from the tree via exiting the application or other means probably causes the crash. Swapping the active camera before removing one could be a work around.
