Thanks. I watched how histogram.cpp is written. Perhaps, I should RTFM carefully before mailing. The obstacle was: API had changed so that I have to use boost::variate_generator to get working rng functor, and not to use some_distribution<> directly. Though I have not read enough now why I have to do so. Roman.

...

I observe boost::normal_distribution always return "nan" with all RNGs whereas other distributions behave normally. I'm talking about boost 1.32 - in earlier version boost::random has different interface.

It's working OK in the test suite, do you have a test case?
