Subject: [ruby-core:119171] Re: Segfault using ruby C on MacOS (Intel Catalina and M2 Sonoma)

Update:
I read that "the Ruby VM is not at all thread safe" according to http://silverhammermba.github.io/emberb/c/#ruby-in-c-threads

And I could reproduce that ass soon as I call rb_p in a C pthread it crashes/hangs.

My questions: 
- Is this true for the current Ruby 3.x.x ?
- If so are there plans to make Ruby thread safe ?
- Is there a workaround except creating a ruby thread in C ?

Thanks,
Martin
