merge revision(s) c6f84e918943a0bf8db6fee556fc53180d257510: [Backport #19398]
[Bug #19398] Memory leak in WeakMap
There's a memory leak in ObjectSpace::WeakMap due to not freeing
the `struct weakmap`. It can be seen in the following script:
```
100.times do
10000.times do
ObjectSpace::WeakMap.new
end
# Output the Resident Set Size (memory usage, in KB) of the current Ruby process
puts `ps -o rss= -p #{$$}`
end
```
