I can confirm this.

If I replace the for...do...end with the equivalent chunk of pseudocode
from section 2.4.5 of the manual, it all works as expected.

arg is a Lua 5.0-ism. Lua 5.1 has a backwards compatibility option,
which by default is turned on. LuaJIT 1 had this option which was by
default turned off --- LuaJIT 2 appears not to have it at all.

Use {...} instead of arg and it all works.

Again, these are Lua 5.0-isms that are now deprecated in Lua 5.1. Use
#table instead.
