Issue #17196 has been reported by asuper (Anthony Super).

----------------------------------------
Bug #17196: Segmentation Fault with Socket#close in Ractors
https://bugs.ruby-lang.org/issues/17196

* Author: asuper (Anthony Super)
* Status: Open
* Priority: Normal
* ruby -v: ruby 3.0.0preview1 (2020-09-25 master 0096d2b895) [x86_64-linux]
* Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN
----------------------------------------
While messing around with 3.0.0-preview1, I thought it would be fun to write a really, really simple webserver that used Ractor creation instead of forking or spawning threads. I was right, it was fun! Unfortunately it also caused a segfault. The segfault appears to be on socket closure when a *lot* of ractors are running at once.

The attached tarball includes the code you need to make it happen. Run `bin/server` in one terminal/screen session/tmux window/whatever, and `./bug_bench.sh` with the other. You'll need to have the apache benchmark utility installed.
