Minimal program for reproducability - leads to access violation

Not sure if this is limited to the joystick subsystem,
but I created a minimal program for reproducibility,
which is attached.

The issue occurs with my gamepad Razer Onza (an xbox-style gamepad) plugged in.
On initialization, the gamepad is being recognized.
After quitting the subsystem, the poll will receive the joystick added event,
which it instantly handles itself, calling SDL_SYS_JoystickDetect again,
which this time calls IDirectInput8_EnumDevices with dinput = NULL (after it was released on quit).
This seems to lead to an access violation within said function, which I have no source for.

The issue was originally noticed on ET:Legacy, after its switch from SDL1 to SDL2 (2.71 RC4 to 2.71a).
The issue I reported is available at
http://dev.etlegacy.com/issues/757
and also includes stack traces of the issue there.

However, for reproducibility and program flow,
the attached example is probably easier to work with.
The issue only occurs with the delay before the subsystem quit call.

I tested this with ET:Ls lib repository 2.0.3 version of SDL
(binaries)
https://github.com/etlegacy/etlegacy-libs/tree/master/sdl2-windows
a self-compiled debug version of 2.0.3 also from their source
https://github.com/etlegacy/etlegacy-libs/tree/master/sdl2

and then downloaded and compiled from HG 817656bd36ec from http://hg.libsdl.org/SDL

The issue occurred in all three occasions.
