1. when there were some engines with ref > 1 in the cache, prior to calling
QFontDatabase::{add,remove}ApplicationFont()/removeAllApplicationFonts()
(QFontCache::clear() has never decreased engine's cache_count);
2. when the QFontEngineData's engine is not in cache i.e. the Box or Test font engine
(~QFontEngineData() didn't free engines it keeps).
Instead of using the font engine's (external) "cache_count" counter,
QFontCache now references a given font engine every time it is inserted to
the cache and dereferences exactly that number of times in clear().
