[Interest] known issues with QFontDatabase::addApplicationFontFromData in Qt/Mac 5.9?

Perhaps you can simply use your Info.plist to point to a folder of fonts, and not use Qt to add fonts to the database:

	<key>ATSApplicationFontsPath</key>
	<string>../../../Fonts Folder</string>

Or, if you want to load them from your bundle, put them in (for example) Your.app/Contents/Resources/Fonts, the value is only the bit after Contents/Resources, namely "Fonts".

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):
