I'm trying to reuse a old library to generate poisson numbers. In old  context versions the library works fine, but in the current  beta (ConTeXt  ver: 2015.07.16 13:30 MKIV beta  fmt: 2015.7.23  int: english/english) the execution fails. 

This code works perfectly in lua 5.3 but not in luatex. why?

\startluacode


require "meurandist"
ARRAY_SIZE=3
arr=meurandist.new_int(ARRAY_SIZE)
meurandist.rpoisson(arr,ARRAY_SIZE,4)
for i=0,ARRAY_SIZE-1 do
print(meurandist.int_getitem(arr,i))
end


\stopluacode


Thanks a lot



luatex 0.80.1 (the latest luatex) still uses lua 5.2.4
