Bug #20311: Struct.new("A") memory leak?
https://bugs.ruby-lang.org/issues/20311
* Author: MaxLap (Maxime Lapointe)
* Status: Open
* ruby -v: 3.3.0
* Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN
----------------------------------------
The following code gives the impression of a memory leak.
```
10.times do
5000.times do
Struct.new("A")
Struct.send(:remove_const, :A)
end
GC.start
puts `ps -o rss= -p #{$$}`.to_i
end
```

66144
73764
81196
88512
95752
```
Is there another location where the struct gets set that I need to clear up for the GC free the memory?
Happens in 3.2.2, 3.2.3, 3.3.0, 3.3-head, ruby-head.
