A [recent built on the nixos build server hydra](https://hydra.nixos.org/build/122996414/nixlog/1) failed with this error for `statistics-0.15.2.0`:

My best guess is, that this is not indicative of a bug in the library. Maybe the eps is to small?
I don‘t assume that this is the result of linking against a wrong library version or something, i.e. a issue in nixpkgs. But please enlighten me.
