### Issue

There are plenty of discussion on this, but they are spread over multiple PRs, that typically get outdated. Let's use this to keep track of everything.

This is quite important as it is now blocking:
* robostack rebuilds https://github.com/RoboStack/ros-humble/pull/206
* conda-forge migrations https://github.com/conda-forge/ompl-feedstock/pull/42

## Detailed description

Since boost 1.84 migration (see https://github.com/conda-forge/ompl-feedstock/pull/35, the previous pinned version was 1.82) two tests are failing:

~~~

Start with tests/base/planner_data.cpp and tests/control/planner_data.cpp, especially the Serialization cases reported in the issue, then inspect the corresponding PlannerDataStorage.cpp load paths. Run test_planner_data and test_planner_data_control with Boost 1.86 on macOS; done means both serialization tests pass without input-stream errors or memory-access failures.
