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

Submitter withdraws defect.

Proposed resolution:

Change 28.5.6 [rand.predef]/p6:

typedef discard_block_engine<ranlux48_base, 389, 11> 

Required behavior: The 10000th consecutive invocation of a default-constructed object of type ranlux48 shall produce the value 249142670248501 88229545517833.
