I've made a font for testing on Kazuki's advice using AFDKO. You can download it from here: https://dl.dropboxusercontent.com/u/5807100/SourceHanSans-Medium-Reduced.ttc
If you compile the attached luaotfload_test.tex with plain-LuaTeX 0.81.0, you will get this error: <./SourceHanSans-Medium-Reduced.ttc(SourceHanSans-Medium:-1)Invalid TTC index number After applying the patch Kazuki submitted yesterday to fontloader, this source can be compiled correctly. Sincerely, Yusuke Terada
