Indeed, but it is the hard fact of life.

Lua used to allow all options and extensions available in the C library
without looking at them, but some C libraries do crash when fed unknown
options, and now Lua checks them and unfortunately cannot handle all
extensions.

See checkoption in loslib.c and lua_checkmode in liolib.c.
