Subject: [ruby-core:34419] [Ruby 1.9-Bug#4272] rb_enc_str_new() causes segmentfault when using threads in parallel

Issue #4272 has been updated by I��aki Baz Castillo.


It's interesting the fact that (using my attached C extension) the following code doesn't crash:

  times.times do |num|
    tester.test_rb_str_new
    threads << Thread.new { }
  end

but the following codes DO crash:

  times.times do |num|
    tester.test_rb_str_new.inspect
    threads << Thread.new { }
  end

  times.times do |num|
    a = tester.test_rb_str_new
    threads << Thread.new { }
  end
