Traces of dinput device test on wine-0.9.49-199-ga529ef4

This is the dinput device test crashing when the "joystick" (actually a
keyboard) I mentioned in comment #27 is connected. I made two runs with
different WINEDEBUG options.
In both runs, the program dies due to a read access to 0x55555555, i.e. it
somehow dereferenced uninitialized "in-use" memory.

In the first run, the backtrace when compiling with -g3 reveals that a
parameter to JoystickAImpl_GetObjectInfo is wrong:
  3 0x606d8e69 JoystickAImpl_GetObjectInfo+0x40(iface=0x11f880,
pdidoi=0x34f7d4, dwObj=0x55555555, dwHow=0x2)
[/home/Lionel_Debroux/wine/dlls/dinput/joystick_linux.c:989] in dinput
(0x0034f7a8)
  4 0x606ccb92 IDirectInputDevice2AImpl_EnumObjects+0x1ae(iface=0x11f880,
lpCallback=0x60683160, lpvRef=0x34f95c, dwFlags=0x0)
[/home/Lionel_Debroux/wine/dlls/dinput/device.c:860] in dinput (0x0034f938)

In the second run, a parameter to _dump_dinput_GUID is invalid:
=>1 0x7eb9e8f8 _dump_dinput_GUID+0x52(guid=0x55555555)
[/home/Lionel_Debroux/wine/dlls/dinput/device.c:181] in dinput (0x0034f758)
  2 0x7eb9ee17 _dump_DIDATAFORMAT+0x4de(df=0x11fb68)
[/home/Lionel_Debroux/wine/dlls/dinput/device.c:212] in dinput (0x0034f828)
