Because an out-of-memory error in the interpreter (in BC_TDUP) should be caught by pcall and it shouldn't crash, either. A simple test works for me: $ luajit -joff -e "collectgarbage('stop'); print(pcall(function() for i=1,1e9 do t={1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20} end end))" false not enough memory --Mike
