Crash Win32 Chibios1760 + ugfx

[cryptobeat]

Hi

I'm getting crash running under Simulator Chibios 1760 + ugfx. Works fine under Chibios 1615 + ugfx

Please see attached project.

Crash happens inside this file: gdisp_lld_Win32.c:

 

      mousemove:
         if (priv->capfn) ///////capfn must be null but under 1760 it 's not
            priv->capfn(hWnd, g, btns, (coord_t)LOWORD(lParam), (coord_t)HIWORD(lParam));

It crashes because it looks like mouse structure initialization overruns the memory in here setting value of the capfn in mouse structure

   

   #if GFX_USE_GINPUT && GINPUT_NEED_MOUSE
      priv->mouseenabled = hWndParent ? FALSE : TRUE;
      priv->mouse = (GMouse *)gdriverRegister((const GDriverVMT const *)GMOUSE_DRIVER_VMT, g);
   #endif

Any advise?

Thank you!

Hi,

Thank you for bringing this to our attention. I'll leave to that to @inmarket as he's the one who wrote the win32 driver(s).
