Hi Ben! I didn't notice any message from you yet on this bug that is blocking your package from migrating to testing: https://tracker.debian.org/pkg/recastnavigation
What did you have planned as your next steps? To me this symbol "_Z15rcBuildP..." looks like an internal private symbol that should not have been exposed by the library in the first place, but I don't have deeper insight in how the ABI of this package works.
