Weird Lua bug(?)

Was attempting to write an ETHIOPIAN NIGGER-SCALE SOLUTION to the problem posed by the OP of this thread: http://dis.4chan.org/read/prog/1195330684/ when I ran into a really odd bug:
n,t=io.read("*number"),{}
while n~=0 do table.insert(t,n) end
for i,v in ipairs(t) do print(i,v) end

Run this code, it will prompt you for a number, enter one and hit return: it will eat as much memory and CPU cycles as possible.

What the shit?

WORD TO THE WISE, IF ANYONE STARTS A POST WITH "In the Haskell type system" IGNORE THEM!!!!!!!!!!!!!!!!!!!!!
