Above issue has been fixed, along with another segfault, with some very appriciated help from the pybind11 devs. Unfortunately the fix is Linux and GCC specific (please see this issue), but I do aim to make it work with multiple compilers and platforms.

Only two issues remain under the first-release tag; a reviewal of the Libgen parser and the writing of proper CMake installation targets. A friend of mine has offered to do some QA before I tag a release. Hopefully no too serious bugs will appear.
