Subject: [ruby-core:102424] [Ruby master Bug#17612] ractor crash with some simple codes
Issue #17612 has been updated by tomanderson (Thomas Ender).
@ko1 Here is my error log when running your simpler code:
irb(main):036:0> 2.times.map{ Ractor.new{ loop{ rand.to_s } } }.each(&:take)
<internal:ractor>:267: warning: Ractor is experimental, and the behavior may change in future versions of Ruby! Also there are many implementation issues.
*** Error in `irb': free(): invalid next size (fast): 0x00007f69a0001490 ***

FYI, my environment is ruby 3.0.0 installed by rbenv, OS is ubuntu 16.04 desktop x64. My example was firstly found crashed in Rails, but later I put it into .rb and run script with ruby, it crashed in the same way. I also test it on windows 10 with ruby 3.0 installed by rubyinstaller.org version and seems to be the same.

Bug #17612: ractor crash with some simple codes
https://bugs.ruby-lang.org/issues/17612#change-90296
* Author: tomanderson (Thomas Ender)
* Status: Assigned
* Priority: Normal
* Assignee: ko1 (Koichi Sasada)
* 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.
