MacOS crash on SDL_PumpEvents

[cclark25]

Description of the crash:

When launching the application on MacOS, there are sporadic crashes when a game control activates input.
Using a debugger, it appears that this is due to a segfault produced by various different calls to SDL_PumpEvents. The primary location where this is is happening appears to be libultraship/src/controller/deviceindex/ControllerDisconnectedWindow.cpp:17.

Can you reproduce? If so please list the steps:

• No, I cannot reproduce this crash
• Yes, here are the steps to reproduce the crash:

1. Launch the application on MacOS.
2. While launching, activate any controller endpoint.
3. If the crash doesn't occur, try again. This sometimes doesn't happen until around the 10th attempt, and other times it happens nearly every time the app is launched.

I tried to figure out how to resolve this, but I was unable to find anything.
The PumpEvent calls are producing segfaults even when I confirmed that they are called on the main thread, which is the same thread that is Init-ing the SDL subsystems.
I also confirmed that SDL_WasInit is reporting that the subsystems were initialized prior to the segfaults.
I also couldn't find anything online related to this issue either.

I just confirmed that this issue is not happening on the Linux build.
The chances seem strong that this is a weird condition specific to MacOS.

This could possibly be related to this issue on the SDL repo: libsdl-org/SDL#9042
It may be possible to resolve this by upgrading the SDL version of the app, which I am not sure how to do here.

This appears to only happen with my Logitech Wireless Gamepad F710.
I have connected my Switch Joycons as a controller and don't see the same issue.

Updating SDL would be Libultraship's responsibility. It might be worth it to this on SoH and if it happens there, open an issue on libultraship.
