This could well be the case. The following works fine on OSX

gResult = false or "anything else";
io.stdout:write("gResult = '"..tostring(gResult).."'\n");

local lResult = false or "anything else";
io.stdout:write("lResult = '"..tostring(lResult).."'\n");

local xResult = false;
local tResult = xResult or "anything else";
io.stdout:write("tResult = '"..tostring(tResult).."'\n");

Giving:

gResult = 'anything else'
lResult = 'anything else'
tResult = 'anything else'
