I'm not certain if the behavior I'm seeing is expected or a problem.
I'm getting different series of numbers from the two different boost versions in question.
The change is actually in Boost 1.64 which "improved the normal distribution" with https://github.com/boostorg/random/commit/c7d1b4f3516098b3e2fc8f8531d716881a... Discussion is in https://github.com/boostorg/random/pull/23 Other seem to have noticed the changed behavior too: https://github.com/stan-dev/math/pull/601 Steven has to determine whether this is a regression or an (semi-)intended side effect. But AFAIK random number generators/distributions are not guaranteed to generate the same numbers using different versions of the library. Alex
