【未解決】Docker イメージの ruby:2.5.0-alpine3.7 で stack level too deep が出る理由が分からない

Last updated at Posted at 2017-12-28

わからない。

以下、rubocop 実行時に遭遇したケースを強引に再現。
別途 rspec 実行時にも遭遇したので、rubocop 固有の問題ではないはず。

Alpine Linux 3.7 (musl) のスレッドスタックサイズが glibc と比べて小さい(80k)事で、Ruby 2.4.3 では発生しないが Ruby 2.5.0 では発生する、という実行環境固有の問題と考えるべきだろうか。

ruby:2.5.0-alpine3.7

[docker-for-mac]% docker container run --rm -it ruby:2.5.0-alpine3.7 sh

# gem install rubocop
# cat <<\RUBY > sample.rb
require 'rails_helper'

RSpec.describe MyClass do
  describe '#my_method' do
    subject { MyClass.new.my_method(arg) }

    context 'when ...' do
      context 'when ...' do
        context 'when ...' do
          context 'when ...' do
            let(:arg) { create(:arg, :trait, attr: x) }

            it 'should be ...' do
              YourClass.new(
                x: X.x(
                  y: Y.y(
                    z: Z.z(
                      a: A.a(
                        b: B.b
                      )
                    )
                  )
                )
              )
            end
          end
        end
      end
    end
  end
end
