Oddly enough https://ci.rvm.jp/results/trunk_asan@ruby-sp1 doesn't fail.
This is not the first time, it's been many times that job found issues not caught in ruby/ruby CI, so I would like to request adding a ASAN GHA job doing the same as https://github.com/ruby/ruby-dev-builder in ruby/ruby so such failures are found earlier and do not block ruby-dev-builder and setup-ruby.
If not, I will be forced to drop ASAN support in setup-ruby.
For now I will exclude these tests on ASAN to unblock, but it's a bit hacky because there seems to be no predicate to detect ASAN, except `Thread.asan?` with `require '-test-/stack'` (= hacky).
