--- Comment #6 from Jonathan Wakely <redi at gcc dot gnu.org> ---
I don't think this is a bug, the result of uniform_real_distribution depends on
floating point arithmetic which depends on optimisations.

The output of the mt19937_64 engine is portable between different
implementations, but the output of the distributions is not.
