CMake stores a check_type_size result as two cache entries: HAVE_<VAR>, documented as Result of TRY_COMPILE, and <VAR>, documented as CHECK_TYPE_SIZE. The exporter only recognized the first, so a seeded configure restored HAVE_<VAR>=TRUE, skipped the probe and had no size. Seed the size entry too, and hash tools/configure_seed.py into the seed cache key so a seed written by the old exporter is not restored.
