           Summary: VirtualDJ 2024: crashes when USB Midi controller is
                    connected
           Product: Wine
           Version: 9.19
          Hardware: x86-64
                OS: Linux

Terminal output

Application Name: VirtualDJ
Application version: v2024 b8308

Summary

Application crashes with unhandled page fault.


Steps to reproduce

1. Install the application to a new Wine prefix.
2. Run setup_dxvk install to have Vulkan based DirectX API.
3. Connect the DDJ-FLX 10 controller via USB to the computer (as the only
hardware midi device). 
4. Start the application.
5. The main application window appears. Few seconds later it crashes with
unhandled page fault.


Application log is created with
+pid,+tid,+hid,+winmm,+setupapi,+alsa,+midi,+mcimidi,+driver debug channels.
> From the address that the application tried to read from seems to be the dwUser
> argument of the DriverCallback() function.
> That comes from the dwClientInstance of WINE_MLD structure. It seems to
> originate from the midiOutOpen() call, but I don't see how or where it did
> change, because the error message shows a different address.
