Subject: [ruby-core:116019] [Ruby master Bug#19411] GC issue with moved objects
Date: Thu, 04 Jan 2024 22:29:18 +0000 (UTC) [thread overview]
Message-ID: <redmine.journal-106009.20240104222918.3573@ruby-lang.org> (raw)
In-Reply-To: redmine.issue-19411.20230203215948.3573@ruby-lang.org

----------------------------------------
Bug #19411: GC issue with moved objects
https://bugs.ruby-lang.org/issues/19411#change-106009
* Author: luke-gru (Luke Gruber)
* Status: Open
* Priority: Normal
* ruby -v: 3.2.0
* Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN
----------------------------------------
This crashes:
```ruby
class Obj
def initialize
@obj = 3
end
end
GC.stress = true
r = Ractor.new do
obj = receive
p obj
end
obj = Obj.new
r.send(obj, move: true)
r.take
```
It only crashes with nested objects, if you remove the ivar set in `initialize` it works fine. Maybe missing `RB_GC_GUARD`?
