Hello,
getting a crash with the following relevant part in the stack trace thereafter.
It works fine on Windows & Linux, both with freetype and with the same font (Ubuntu).
It also works fine in the same case with the cocoa fontengine on macOS.
I am sourcing the font from a QRC, adding it with
int id = QFontDatabase::addApplicationFont(":/Ubuntu-R.ttf");
beforehand.
QFontDatabase::applicationFontFamilies(id);
prints me ("Ubuntu").
Here's the trace :
