Semiwrap / meson / robotpy define `NDEBUG` when building their software in all modes, while `allwplib` only does it when building debug. This causes the size of `DenseMap` to differ between the shared libraries built here, and the extension modules built in `mostrobotpy`, causing segfaults when you try to execute code that uses `DenseMap`. This is not a problem with the robotpy code in `allwpilib`, because bazel uses the exact same compiler flags when building the shared libraries and pybind11 extensions.
