https://bugs.ruby-lang.org/issues/13605#change-66023
* Author: ryanf (Ryan Fitzgerald)
* Status: Closed
* Priority: Normal
* Assignee:
* Target version:
* ruby -v: ruby 2.4.1p111 (2017-03-22 revision 58053) [x86_64-linux]
* Backport: 2.2: DONTNEED, 2.3: DONTNEED, 2.4: DONE
----------------------------------------
This code made Ruby bail out with the message "[BUG] rb_gc_mark(): 0x000000040dc740 is T_NONE":
~~~ ruby
ObjectSpace.each_object(Module){|m|
next if (to_ignore.include?(m) rescue true)
if m.respond_to?(:instance_methods)
candidates.concat m.instance_methods(false).collect(&:to_s)
end
}
~~~
I haven't been able to repro, but it happened building Pry on Travis CI: https://travis-ci.org/pry/pry/jobs/236720971
The relevant logs are attached.
