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

[René J.V. Bertin]

Hi,

Is there a known issue when using QFDb::addApplicationFontFromData() or QFDb::addApplicationFont() with an embedded resource path in Qt 5.9 on Mac? 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):

Thanks,
