I build qt windows x64 from the latest git 5.8.0 branch. Now each qt app will assert in text\qfontdatabase.cpp, line 425
ASSERT failure in void __cdecl QtFontFamily::ensurePopulated(void): "SimSun", file text\qfontdatabase.cpp, line 425
I use windows 10 x64 simplified chinese.
I have fixed a similar issue in the past, https://codereview.qt-project.org/#/c/107127/, It seems that this issue has been retriggered in qt-5.8.0
