05:44 AM Ruby Feature #21084 (Open): Declare objects have weak references

I don't think this works correctly with generational GC. This crashes reliably on HEAD (works fine on 4.0.0)
``` ruby
wmap = ObjectSpace::WeakMap.new
GC.disable # only manual GCs
GC.start
GC.start
retain = []
50.times do

08:06 PM Ruby Revision d9c0d4c7 (git): Don't copy invalidated CME in rb_vm_cc_table_dup

The cc_entries list associated with the invalidated CME can be deleted
from the table during GC, so it isn't safe to copy (and we shouldn't
copy it anyways, it's stale data). jhawthorn (John Hawthorn)
