[ruby-core:114379] [Ruby master Bug#19836] Parser leaks memory for incomplete lambdas

From: "peterzhu2118 (Peter Zhu) via ruby-core" <ruby-core@...>
Date: 2023-08-09 16:24:29 UTC
List: ruby-core #114379
Issue #19836 has been reported by peterzhu2118 (Peter Zhu).

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

* Author: peterzhu2118 (Peter Zhu)
* Status: Open
* Priority: Normal
* Backport: 3.0: REQUIRED, 3.1: REQUIRED, 3.2: REQUIRED
----------------------------------------
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
```
