Bug #18928: Crash in WeakMap when inspecting T_FREE objects
https://bugs.ruby-lang.org/issues/18928
* Author: peterzhu2118 (Peter Zhu)
* Status: Open
* Priority: Normal

----------------------------------------
Pull request: https://github.com/ruby/ruby/pull/6152
WeakMap tests occasionally crash on CI due to trying to inspect T_FREE objects. There's a bug in `wmap_live_p` that returns true for dead objects that are in the tomb heap or on pages that are already freed.
Here's a crash log:
```

Pull request: https://github.com/ruby/ruby/pull/6152
WeakMap tests occasionally crash on CI due to trying to inspect T_FREE objects. There's a bug in `wmap_live_p` that returns true for dead objects that are in the tomb heap or on pages that are already freed.
Here's a crash log:
