--- Comment #1 from Nikolay Sivov  ---
This looks like an application bug:

---
0024:trace:d2d:d2d_factory_CreateDrawingStateBlock iface 036F1B50, desc
00000000, text_rendering_params 00000000, state_block 11BE6AB8.
0024:trace:d2d:d2d_factory_AddRef 036F1B50 increasing refcount to 182.
0024:trace:d2d:d2d_factory_CreateDrawingStateBlock Created state block
0BCB3D30.
0024:trace:d2d:d2d_device_context_SaveDrawingState iface 0BCB34B0, state_block
11BE6AB8.

Instead of passing interface pointer to SaveDrawingState(), it's passing same
out pointer.

Removing assertion helps.
