           Summary: dinput-remap-joystick causes crash with >32 button
                    joystick
           Product: Wine-staging

Log of `wine control joy.cpl` when crashing due to button 33 being pressed
When the `dinput-remap-joystick` staging patch is applied to Wine, various
crashes occur with a joystick that has more than 32 buttons.
* Wine's `joy.cpl` crashes when pressing or releasing such a button
(Wine-Staging)
* Star Citizen crashes during launch (Wine-Staging + DXVK)
`joy.cpl` works fine in vanilla Wine. Star Citizen requires other staging
patches to launch, and works fine if `dinput-remap-joystick` is excluded.
I'm using the Saitek X-55 Rhino HOTAS, where the throttle and stick can be
plugged in independently. The throttle has 34 buttons and causes these crashes,
the stick only reports 17 buttons (14 physically) and does not cause any
crashes. Buttons 32-34 on the throttle are the three-state "MODE" switch (M1-M3
respectively).
The crashes in `joy.cpl` happen regardless of whether the `(event)` or `(js)`
interface of the throttle is selected.
