I don't know whether this is a problem of luatex or of my Linux, but with the latest version I get this message from the operating system (because it is in Spanish)

javier@javier-laptop:~$ luatex
Excepción de coma flotante
javier@javier-laptop:~$

i.e., "floating point exception". I do not even see the "This is Luatex... " message.
