[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
