Failing tests with ruby-head about sinatra

[dentarg]

Maybe ruby/ruby#9460

So d6294df didn't help, that's interesting

We have more fails, sinatra tests too: https://github.com/sinatra/sinatra/actions/runs/7476448903/job/20346834173#step:5:25

Maybe this one

sinatra/test/routing_test.rb

Lines 763 to 766 in fa5a139

	get '/this/is/a/test/'
	assert ok?
	assert_equal 'right on', body
	end

Clearly a bug IMO. That line doesn’t mutate that interpolated string.

So it should be reported to https://bugs.ruby-lang.org/, but it would be good to have a smaller reproducer for that.

I don't have ruby-head built locally and rubylang/ruby:master-nightly-bionic (docker image) isn't up-to-date

root@12277fb5a008:/app# ruby -v
ruby 3.3.0dev (2022-12-26T15:28:38Z master a968d783a3) [x86_64-linux]

I guess I could try to build that image myself though, not sure when I get to it though.

master-nightly-jammy doesn't cut it? It was last built 3 hours ago: https://hub.docker.com/layers/rubylang/ruby/master-nightly-jammy/images/sha256-629a6b60bceb263049c8b6b6e48dbd637356794f481da90f7abfcd1574a57dac?context=explore

@byroot Oops, of course 🤦 didn't think that through. Thanks.
