    context 'you' do
      context 'use' do

          context 'magic' do
            context 'of' do
              context 'rspec' do
                context 'too' do
                  context 'much' do
                    it 'blows up when rendering the Failure :(' do
                      expect(1).to eq(2)
                    end
                  end
                end
              end
            end

We encountered this issue and it caused some sads 😢

Thanks for reporting this! @yujinakayama, this looks like it's happening in snippet extraction support code you added. Can you take a look?

[yujinakayama]

Hmm, I could not reproduce it.

[craigjbass]

yeah this is strange.

I found it did work natively on my machine, but within Docker there seems to be a much smaller stack limit

This is my Dockerfile

FROM ruby:2.5.0-alpine3.7

RUN apk add --update alpine-sdk postgresql-dev postgresql-client

WORKDIR /app
COPY Gemfile ./
COPY Gemfile.lock ./
RUN bundle install

RUN apk del alpine-sdk

ADD . /app

EXPOSE 4567
EXPOSE 1234
CMD ["bin/serve.sh"]

[craigjbass]

My .rspec flags:

--format documentation
--color

[craigjbass]

I'm using the patch in #343 against my production code, and I don't get the error anymore.

[craigjbass]

Here's a repo with a minimal reproducible example: https://github.com/craigjbass/rspec-stack-level-too-deep

Note: I've struggled with flakiness around this depending on whether run in Docker / natively / enough nesting

For people coming here via google: There's also this ruby issue about a stack level too deep error on alpine/docker. This might still bite you even with rspec 3.7.1!

[craigjbass]

Indeed @jayniz - this is caused by Alpine’s use of musl libc instead of glibc which has a stack size of 80k. There is an API to tell musl to increase the stack size, but Ruby does not know how to call this. (Yet)
