This looks like the segvs we were observing, which was fixed by https://bugs.ruby-lang.org/issues/17539 (and PR https://github.com/ruby/ruby/pull/4066).
@tenderlovemaking (Aaron Patterson) can you confirm?

I'm not certain. Ours was failing inside the GC code. Here it fails in vm_method.
@vo.x (Vit Ondruch) are you able to trigger this bug consistently?
Updated by vo.x (Vit Ondruch) over 3 years ago
Yes, I can hit it every time. And I am testing the patch efcdf68e6443ab70fbff1703b9dabbfc5090df31 and it does not fix the issue.

Just FTR, the reproducer I have is trying to execute shoulda-matchers [1] test suite such as:
$ bundle exec rspec spec/unit/shoulda/matchers/action_controller/set_flash_matcher_spec.rb
I guess the reproducer should be possible to reduce further down to the Rails app, which is constructed via these test cases, but it is unfortunately quite complex. Maybe I should propose to add ruby-head to shoulda-matchers upstream.

Is this error the expected behavior?
Updated by vo.x (Vit Ondruch) over 3 years ago
It is reproducible on every platform.
We had to hack the test suite a bit to make it work on Fedora. The full script is here 1, but the relevant part should be this:
# It is easier to recreate the Gemfile to use local versions of gems.
cat << GF > Gemfile
source 'https://rubygems.org'
gem 'bcrypt'
gem 'rails'
gem 'rails-controller-testing'
gem 'rspec'
gem 'rspec-rails'
gem 'sqlite3'
gem 'spring'
GF
# Pry is useless for our purposes.

spec/support/acceptance/helpers/step_helpers.rb
bundle exec rspec spec/unit
It removes some dependencies and dependencies on specific versions and I think the seds should take care about the appraisals.

I should also mention that there is currently Rails 6.0.3.4.
Updated by tenderlovemaking (Aaron Patterson) about 3 years ago
I was able to reproduce this, but it's hard to make a small script to reproduce the issue.
Here is the program I used to reproduce the issue:
require 'bundler/inline'
gemfile do
source 'https://rubygems.org'
gem 'rails', '= 6.0.3.4'
end
require "action_controller/railtie"
class App < Rails::Application
config.eager_load = false
routes.append do
get "/hello/world" => "hello#world"
end
end
App.initialize!
500.times do |i|
controller_class = Class.new(ActionController::Base)
controller_class.new
controller_class = nil
Rails.application.reload_routes!
end
The bug is that Ruby is trying to clear method caches on an ICLASS during incremental sweeping. But the ICLASS is actually a garbage object (the ICLASS will be swept during incremental sweeping).
Here is the backtrace:

If we go to frame 9 and look at the object that is having it's cache cleared, it looks like this:
(lldb) command script import -r ~/git/ruby/misc/lldb_cruby.py
lldb scripts for ruby has been installed.
(lldb) f 9

162 else {

164
165 if (cme) {
166 // invalidate cme if found to invalidate the inline method cache.

super = 0x000055aab4752858
ptr = 0x000055aab4828110
class_serial = 6254
}
(lldb)
Note that the object has no flags. In other words, this class object is not marked. If we examine object space, we can see that the GC is currently in mode 2:
(lldb) p ruby_current_vm_ptr->objspace->flags
(rb_objspace::(anonymous struct)) $2 = {
mode = 2
immediate_sweep = 0
dont_gc = 0
dont_incremental = 0
during_gc = 0
during_compacting = 0
gc_stressful = 0
has_hook = 0
during_minor_gc = 1
during_incremental_marking = 0
}
Mode 2 is lazy sweeping. So the GC is currently sweeping pages. If we check the page that this object lives on, it looks like this:
(lldb) heap_page klass
(struct heap_page *) $4 = 0x000055aab4815bf0
(struct heap_page) $5 = {
total_slots = 409
free_slots = 0
pinned_slots = 0
final_slots = 0
flags = {
before_sweep = 1
has_remembered_objects = 0
has_uncollectible_shady_objects = 1
in_tomb = 0
}
free_next = 0x000055aab47fe040
start = 0x000055aab4818008
freelist = 0x0000000000000000
page_node = {
next = 0x000055aab4828a28
prev = 0x000055aab47fe068
}
wb_unprotected_bits = ([0] = 0, [1] = 0, [2] = 0, [3] = 0, [4] = 0, [5] = 0, [6] = 1048576)
mark_bits = ([0] = 17887750712806752255, [1] = 13114482114902867966, [2] = 18445585177834129919, [3] = 14877641359354736639, [4] = 18304601297856232382, [5] = 4758088225044815998, [6] = 16676486)
uncollectible_bits = ([0] = 17887750712806752255, [1] = 13114482114902867966, [2] = 8933982764827640319, [3] = 14859626960845254652, [4] = 18304601297856232382, [5] = 4758088225044815998, [6] = 16676486)
marking_bits = ([0] = 0, [1] = 0, [2] = 0, [3] = 0, [4] = 0, [5] = 0, [6] = 0)
pinned_bits = ([0] = 0, [1] = 0, [2] = 0, [3] = 0, [4] = 0, [5] = 0, [6] = 0)
}
The page that this object lives on has its "before_sweep" flag set to true. This means that the GC hasn't swept this page yet, but it will sweep this page. Any objects that are on this page that aren't marked are garbage objects. In other words, the iclass object that lives on this page is garbage. We should not be invalidating cache on objects that are garbage (and that is the bug).
I've pushed a fix here: https://github.com/ruby/ruby/pull/4077
If CI comes back green I'll merge it in.
Thanks!

Don't try to clear cache on garbage objects
Method cache can be cleared during lazy sweeping. An object that will
be collected during lazy sweep should not have it's method cache
cleared. Soon-to-be-collected objects can be in an inconsistent state and
this can lead to a crash. This patch just leaves early if the object is
going to be collected.
