Hi Jens, hi everyone,

I have confirmed that now, thanks to your fixes, the first problem we
were seeing has disappeared. Great!

However, with both gcc-3.2 and gcc-3.3-cvs it is still present a
different run-time failure, which happens for *all* the tests (not only
"minstd_rand") in "birthday spacing". For instance, for boost-cvs and
current gcc-3.3:

paolo:~/Programming/c++/boost-cvs/boost/libs/random> a.out
Confidence level: 0.99; 1-alpha = 0.01; chi_square(19, 36.191) = 0.99

generic_counter<std::vector<int, std::allocator<int> > >]: Assertion
`f.max() == static_cast<result_type>(m-1)' failed.
Abort

Can you reproduce this???

Ciao, Paolo.
