[ruby-core:122943] [Ruby Bug#21537] rb_ractor_sched_barrier_start() hangs on Windows
Issue #21537 has been reported by rhenium (Kazuki Yamaguchi). ---------------------------------------- Bug #21537: rb_ractor_sched_barrier_start() hangs on Windows https://bugs.ruby-lang.org/issues/21537 * Author: rhenium (Kazuki Yamaguchi) * Status: Open * ruby -v: ruby 3.5.0dev (2025-08-09T11:32:53Z master 2a6345e957) +PRISM [x64-mswin64_140] * Backport: 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- The following script hangs at `GC.start` indefinitely. Pressing Ctrl+C on the terminal interrupts the `sleep` and it appears to resume and prints "in_ractor". ```ruby Ractor.new { sleep 1 GC.start puts "in_ractor" } sleep ``` I also reproduced this with Ruby 3.0.7 from RubyInstaller2.
