Bug ID: 38279
           Summary: Uninitialized src_rect in
                    wined3d/surface.c:cpu_blit_color_fill
           Product: Wine
           Version: 1.7.39
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: directx-d3d
          Assignee: [e-mail]
          Reporter: [e-mail]

In procedure cpu_blit_color_fill there is local variable
static const RECT src_rect;
assumed inited by zero?
Then it used as parameter
return surface_cpu_blt(dst_surface, dst_rect, NULL, &src_rect,
            WINEDDBLT_COLORFILL, &BltFx, WINED3D_TEXF_POINT);
And this function explicitly used the pointer
    srcheight = src_rect->bottom - src_rect->top;
    srcwidth = src_rect->right - src_rect->left;

What behavior assumed here?
I found no assingment to this static constant.
