If you build an engine with --enable-impeller-3d then some of the unittests, such as flow_unittests and display_list_unittests will crash. Others may crash as well.

This is likely due to the fact that these tests are compiled in a different target than the display_list sources and so if they are missing the necessary #define then their concept of the vtable for those classes will differ from the version used in the DL sources.
