--- Comment #2 from Esme Povirk  ---
Based on the mingw headers' implementation of FontCollection::GetFamilies, it
seems that GdipCloneFontFamily does something. According to comments, the
example at
https://docs.microsoft.com/en-us/windows/win32/api/gdiplusheaders/nf-gdiplus...
crashes trying to delete the font families, if the wrapper does not clone them.
