Confirmed.  By testing i, your example is compiled:

if i then  -- line 1205 in font-otj.lua
   local leftkern = i.leftkern
   if leftkern and leftkern ~= 0 then
   setfield(prev,"replace",newkern(leftkern)) -- maybe also leftkern
   end
end


i'll add that test

[NTG-context] Luatex 0.95.0 error with bidi and Hebrew

2016-04-30 Thread Rik Kabel 

Version information:

   ConTeXt  ver: 2016.04.30 18:59 MKIV beta  fmt: 2016.4.30  int:
   english/english
   luajittex, 0.95.0 and luatex, 0.95.0

   running on Windows 10 x64

Error message:

   error:
   ...eXt/tex/texmf-context/tex/context/base/mkiv/font-otj.lua:1205:
   attempt to index local 'i' (a nil value)
   tex error   > tex error on line 7 in file
   C://Users/rik/Desktop/comp_body.tex: ?

Code:

   \setupdirections [bidi=global]
   \definefont [hebrew] [default] [lang=heb,ccmp=yes,script=hebr]
   \definefont [Hebrew] [sileotsr*hebrew sa .9]
   \starttext
 \startparagraph
  Hebrew : {\Hebrew רִ}
 \stopparagraph
   \stoptext

When the first line is removed, or the value of bidi changed to on, no 
error is thrown.


A single-font version of the code, for fonts that have Hebrew glyphs, 
fails with some fonts (libertine shown below), but works with others, 
for example, dejavu sans.


Code:

   \setupdirections [bidi=global]
   \setupbodyfont[libertine]
   \starttext
 \startparagraph
  Hebrew : רִ
 \stopparagraph
   \stoptext

My installation, or is this a bug?
