ruby-core #112619
Issue #18119 has been updated by luke-gru (Luke Gruber).
I can't reproduce this on 3.2.0 or 3.3.0-dev (Ubuntu 22.04 x86-64), even with GC.stress = true

Bug #18119: Ractor crashes when instantiating classes
https://bugs.ruby-lang.org/issues/18119#change-102067
* Author: peterzhu2118 (Peter Zhu)
* Status: Assigned
* Priority: Normal
* Assignee: ko1 (Koichi Sasada)
* ruby -v: ruby 3.1.0dev (2021-08-19T08:44:48Z master 6963f8f743) [x86_64-linux]
* Backport: 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN
----------------------------------------
The following script crashes with a segfault (tested on Ubuntu 20.04 and macOS 11.5.2):
```ruby
workers = (0...8).map do
Ractor.new do
loop do
100.times.map { Class.new }
Ractor.yield nil
end
end
end
100.times { Ractor.select(*workers) }
```
Crash error:
```
<internal:ractor>:267: warning: Ractor is experimental, and the behavior may change in future versions of Ruby! Also there are many implementation issues.
