I'm getting a crash; as far as I can tell the CTFontRef creation from the font data succeeds but the CoreText call to fetch the font description crashes, comparable to what happens here except that I can reproduce it by loading font data through the UI):

I remember that adding fonts from resources didn't work for us in 5.8 on 
Mac. We had to ship the fonts in our bundle instead. I didn't check if 
it was fixed in a later version.
