[luatex] bugreport (too late?)

[Élie Roux]

Dear all,

it seems there is a bug in the way TeXLive 2013 LuaTeX handles 
shell-escape (i386-Linux). See the attached files: when running

luatex --shell-escape bug-shell-escape.tex

test 1 should pass, instead it fails: io.popen never works, 
independently of the value of --shell-escape. It used to work before, 
has something changed? Lua manual states that io.popen is system 
dependant and might not be available on all platforms, but I guess the 
error would be different if it was not available...

Thank you,
-- 
Elie
