[ruby-core:121512] [Ruby Bug#21203] TestGc#test_gc_parameter_init_slots is flaky results

From: "mame (Yusuke Endoh) via ruby-core" <ruby-core@...>
Date: 2025-04-02 09:25:05 UTC
List: ruby-core #121512
Issue #21203 has been updated by mame (Yusuke Endoh).


@peterzhu2118 Thanks for working on this issue. Because it's a flaky issue, it is difficult to tell how to reproduce it.

According to Launchable, we can see that

* this issue started occuring around 2025-03-17, and
* it occured on ubuntu-22.04 and ubuntu-24.04-arm with `-DVM_CHECK_MODE`.

https://app.launchableinc.com/organizations/ruby/workspaces/ruby/data/test-paths/file%3Dtest%2Fruby%2Ftest_gc.rb%23%23%23class%3DTestGc%23%23%23testcase%3Dtest_gc_parameter_init_slots?testSessionStatus=fail

I hope it helps.
