Terminal output w/ backtrace

Sonic R starts out by showing a screen with an option to use DirectDraw or
Direct3D. After choosing either one, it produces an error dialog saying "The
instruction at 7e3d53b0 referenced memory at 00000000, the memory could not be
read from" and crashes. DirectDraw worked in 1.1.41 (and Direct3D mode didn't
crash like this) so I did a regression test:

    wined3d: Control the onscreen depth stencil format in the swapchain.

    This allows the swapchain to know what depth format its window contexts
have to see if the
    requested depth format is compatible or a FBO fallback is needed, and it
will be needed to
    set the onscreen format to the requested auto depth stencil format instead
of the
    let's-hope-it-fits D24_UNORM_S8_UINT format.

If you get a division by 0 crash at startup instead, it's a game bug;
workaround is to run something CPU-intensive in the background or otherwise
limit the amount of CPU power available to the game as it starts.
