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
