Do you mind sharing how you are serializing to binary? If you are writing to a file with an `ofstream`, make sure that you specify the `std::ios_base::binary` flag when doing...

You can provide a definition for `CEREAL_RAPIDJSON_NAMESPACE_BEGIN` in `include/cereal/external/rapidjson/rapidjson.h` to override the default behavior. That file has additional explanation on this as well.

Potentially this: https://github.com/USCiLab/cereal/pull/835 In the future include a minimal example along with your compiler error.

What is the structure of `Lemma` and `Form`? If you can't post actual code, can you just describe what they are serializing (and also the sizeof)? Are you using polymorphism?...

We can definitely add a call to `reserve` for `unordered_map` loads.
