I found that LuaTeX 0.95.0 fontloader crashes when input ttf file has a cmap format 13.
AdobeBlank2.ttf freely available from https://github.com/adobe-fonts/adobe-blank-2 has a rare cmap format: <cmap_format_13 platformID="3" platEncID="10" format="13"> When I install it, LuaTeX causes segmentation fault: % luatex test1.tex \directlua{fontloader.open('AdobeBlank2.ttf')}\bye This is LuaTeX, Version beta-0.95.0 (TeX Live 2016/W32TeX) restricted system commands enabled. (./test1.texSegmentation fault: 11 LuaTeX 0.80.0 did not crash with the same font, so there might be an accidental degradation. The issue reported in https://github.com/lualatex/luaotfload/issues/327 with LastResort.ttf (MacOSX bundle) seems to be the same. Hironobu Yamashita
