As you know, lualatex-dev in TeXlive 2019 (after Nov. 2019) will almost the same as lualatex in TeXlive 2020, so I bet this #930292 will remain the same, which of couse I do not welcome... I wonder if this issue (huge memory comsumption with a huge number (e.g. 65535) of glyphs) can be fixed... I understand that lualatex has to examine every pair of all the glyphs, which could be 65535 * 65535 paris... Best regards, Ryutaroh
