[ruby-core:117095] [Ruby master Bug#20330] [BUG] Segmentation fault at 0xffffffffffffffff

10 Mar 2024

      Issue #20330 has been updated by nobu (Nobuyoshi Nakada).

Seems related to shape and jemalloc.
Maybe `parent_index` in `redblack_cache_ancestors` is -1?

Bug #20330: [BUG] Segmentation fault at 0xffffffffffffffff
https://bugs.ruby-lang.org/issues/20330#change-107168

* Author: l33tname (Sir l33tname)
* Status: Open
* ruby -v: 3.3.0
* Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN
----------------------------------------
I get a segfault from ruby on fly.io (a platform to run full stack apps).
As you can see from the stacktracke im using a jemalloc version but im getting the same crash with the 
ruby:3.3.0-slim docker image. (Thats the docker file: https://github.com/Binaergewitter/serious-bg/blob/be890bf6af110b02f22f359d39... based on quay.io/evl.ms/fullstaq-ruby:3.3.0-jemalloc-slim)

Reverting back to ruby 3.2.3 solved the issue for now: https://github.com/Binaergewitter/serious-bg/commit/4eed4119706303383ce5994c...

I was not able to reproduce it locally. 
But the application is open source -> https://github.com/Binaergewitter/serious-bg
