Executing Marshal. load multiple times may cause Ruby program segment errors in arrch64 CPU.

For some reason, I am unable to upgrade to the Ruby version.

Can you help determine if a patch can be applied to this issue? thanks

Ruby 2.2 is too old. We currently support only Ruby 3.0 or later. Please try the newer versions.

I wonder if it's a similar issue to https://github.com/ruby/setup-ruby/issues/496, i.e., 2.2 is too old and miscompiled on recent OS/compiler.
