Hi,
with EB Garamond Italic and contextual ligatures I get a weird
duplicate “s” for the pairing “us”:
·······································································
\starttext
\definefontfeature[default][default][clig=yes]
   \definedfont[ebgaramond12italic*default at 42pt]
   %definedfont[ebgaramond08italic*default at 42pt]
foo us bar ss fi ffi ffl fj\endgraf
Thus, I came to the conclusion ...
\stoptext
·······································································
Occurs in Context and Luatex-Fonts, not only on my machine. Can
some confirm this? Also I’d like to know if that’s a bug in the
font or the font loader.
Thanks
Philipp
[1] Version 0.015 from here:
     http://www.georgduffner.at/ebgaramond/download.html
you can test with

local function s_hashed(t,cache)
     if t then
         local ht = { }
         local tf = t[1]
         for i=1,#tf do
             ht[i] = { [tf[i]] = true }
         end
         return ht
     else
         return nil
     end
end

in font-otf.lua (you need to delete the cached font) - i wonder what the 
original test font was (might as break that one)
