pathname does use `rb_provide`:

No.

In Ruby 3.2, `set` was default gem, and `Set` was an autoloaded constant. The `set` library was not required when a method was called (u... jeremyevans0 (Jeremy Evans)

03:40 AM Ruby Bug #21446: StackOverflow when changing visibility in reopened refinement

I found that you don't even need to change the visibility twice. This issue affects all refinement visibility change methods where the method whose visibility is changed by the refinement is in an ancestor of the refined class. Here's a ... jeremyevans0 (Jeremy Evans)

04:53 PM Ruby Bug #21624 (Third Party's Issue): [BUG] Segmentation fault at 0x0000000000000000

Probably hitting this issue: https://github.com/brianmario/mysql2/pull/1410 . As @luke-gru mentioned, using mysql 0.5.6 should work around the issue until mysql2 releases a fixed gem. jeremyevans0 (Jeremy Evans)

I submitted a PR to make the error messages for & consistent with */**: https://github.com/ruby/ruby/pull/14463 jeremyevans0 (Jeremy Evans)

12:10 AM Ruby Bug #21563: Misleading error message when `to_proc` does not return a Proc in an Object used as a &block argument

If we want to change the behavior in this case, we should report both the actual argument and the return value of `to_proc`. That's what we do for `*a` where `a.to_a` returns non-Array and for `**h` where `h.to_hash` returns non-Hash):

02:13 AM Ruby Bug #21538: initialize_dup not called when duping class/module

I found a simple fix for all issues: https://github.com/ruby/ruby/pull/14412 jeremyevans0 (Jeremy Evans)

12:16 AM Ruby Bug #21538: initialize_dup not called when duping class/module

The example given isn't a bug. `initialize_dup` is called on the new instance (in this example, the instance of `Class`), and `dup` does not copy singleton classes. If you define `Class#inititialize_dup`, it works as expected:
