[Dev-luatex] Floating point exception

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. --Javier A.
