Description RustyM 2020-03-15 18:18:45 UTC 
In the SDL 2.0.12 release, unplugging and then replugging in a controller on macOS will crash. Replugging in a controller seems to lead to a FreeDevice() call that will then crash:

File: joystick/darwin/SDL_sysjoystick.c
Function: static recDevice *FreeDevice(recDevice *removeDevice)
On line 130: IOHIDDeviceUnscheduleFromRunLoop(removeDevice->deviceRef, CFRunLoopGetCurrent(), SDL_JOYSTICK_RUNLOOP_MODE);
Causes: Thread 1: EXC_BREAKPOINT (code=EXC_I386_BPT, subcode=0x0)

This can be reproduced in testgamecontroller by starting the test program with a controller plugged in, removing it, and then plugging it back in. Another way to cause it: remove a controller, then plug in a different game controller.

I've seen this happen on macOS 10.12.6 and 10.14.6. Also on the 2.0.12 release and the latest tip (changeset 13625). Issue seen with multiple controller types, including PS4 and Switch Pro controllers.
