----------------------------------------
Bug #19836: Parser leaks memory for incomplete lambdas
https://bugs.ruby-lang.org/issues/19836#change-104135

* Author: peterzhu2118 (Peter Zhu)
* Status: Closed
* Priority: Normal
* Backport: 3.0: REQUIRED, 3.1: REQUIRED, 3.2: DONE
----------------------------------------
GitHub Pull Request: https://github.com/ruby/ruby/pull/8192

The parser does not free the chain of `struct vtable`, which causes memory leaks.

The following script reproduces this issue:

```ruby
10.times do
  100_000.times do
    Ripper.parse("-> {")
  end

  puts `ps -o rss= -p #{$$}`
end
```
