The rule for using generation 1/2is based on the current memory use versus the maximum size of generation 0. Recent changes to the GC have caused that size to vary during a collection, which means that the choice to use generation 1/2 or not can change within a collection. Partial use of generation 1/2 doesn't inherently cause problems, but it can cause a generation-1 object to point to a generation-1/2 object even though the former was allocated after the latter. That's a problem on if getting generations out of order relative to allocation order can create problems. As it happens, reset_finalizer_tree() checks the generation of the finalization record and not the finalized pointer, because the record is always allocated after the pointer. Merge to v6.3 |
