[ruby-core:115832] [Ruby master Bug#20076] M:N scheduler crashes on macOS with RUBY_MN_THREADS=1

Issue #20076 has been updated by jpcamara (JP Camara). @hsbt is it crashing, or hanging? For me, I am seeing the following tests hang: tool/test/webrick/test_server.rb#test_restart_after_stop tool/test/webrick/test_server.rb#test_port_numbers If I comment those out, `make exam` and `make test-tool` succeed. Is that your experience as well? ---------------------------------------- Bug #20076: M:N scheduler crashes on macOS with RUBY_MN_THREADS=1 https://bugs.ruby-lang.org/issues/20076#change-105786 * Author: hsbt (Hiroshi SHIBATA) * Status: Open * Priority: Normal * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- This is known issue.
