Proposed resolution:

Change [rand.predef]/p6:

typedef discard_block_engine<ranlux48_base, 389, 11> 
        ranlux48
Required behavior: The 10000^th consecutive invocation of a default-constructed object of type ranlux48 shall produce the value ~~249142670248501~~ 88229545517833.

The 10,000^th value returned by ranlux48 is supposed to be 249142670248501. We get 88229545517833. (Note that this depends on ranlux48_base.)
