Hi Jean-Claude,

it is not possible to open /dev/urandom:

(with-open-file (s "/dev/urandom" :element-type '(unsigned-byte 8)) (read-byte s))

Filesystem error with pathname: "/dev/urandom". Cannot open file OS Explanation: (errno == 0) Success [Condition of type SI:OS-FILE-ERROR]

but this works:

(with-open-file (s "/etc/passwd" :element-type '(unsigned-byte 8)) (read-byte s))

Yep! It is a bug!

Working on a fix...

Thanks,
