The crash still happens even if all the tests are commented out except
test_shared_bitmap().
Furthermore adding traces shows that it happens in either of the two locations
below:
https://gitlab.winehq.org/wine/wine/-/blob/f6f66661b3fabdcd6cf2f4999b3029e72...
    /* DXGI surface render target and WIC bitmap render target, same factory.
*/
    hr = ID2D1Factory_CreateWicBitmapRenderTarget(factory1, wic_bitmap2, &desc,
&rt2); // crashed here
or
https://gitlab.winehq.org/wine/wine/-/blob/f6f66661b3fabdcd6cf2f4999b3029e72...
    ID2D1GdiInteropRenderTarget_Release(interop);
    hr = ID2D1Factory_CreateWicBitmapRenderTarget(factory2, wic_bitmap2, &desc,
&rt2); // crashed here
The crashes only happen with 32-bit code.
d2d1:d2d1 also crashes on my box with an Intel GPU and the crash happens in the
same two locations but the backtrace is different.
