Confirmed. My Lua-5.1.4 is fully patched with
http://www.lua.org/ftp/patch-lua-5.1.4-2
and on Linux x86 (32 bits) I  get:

Lua 5.1.4  Copyright (C) 1994-2008 Lua.org, PUC-Rio

true   -- correct

1   -- WRONG

Seems that the patch http://www.lua.org/bugs.html#5.1.4-3  has not
fixed the problem entirely.
