[ruby-core:102416] [Ruby master Bug#17612] ractor crash with some simple codes

Issue #17612 has been reported by tomanderson (Thomas Ender).

----------------------------------------
Bug #17612: ractor crash with some simple codes
https://bugs.ruby-lang.org/issues/17612

* Author: tomanderson (Thomas Ender)
* Status: Open
* Priority: Normal
* Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN
----------------------------------------
I found these codes will crash because of **Ractor** :

``` ruby
    e = (1..1000).to_a
    arr = [e,e,e,e]

    arr.map { |sub_arr|
      Ractor.new(sub_arr) do |sub_arr|
        sub_arr.map {
          Digest::MD5.hexdigest(rand.to_s)
        }
      end
    }.map{|r| r.take}.reduce(:+)
```

If change e to (1..100), no crashes any more. If we don't use Ractor, it's also good.

Environment: ruby3.0.0p0 + rails6.1.1.
