Issue #16920 has been updated by jeremyevans0 (Jeremy Evans). Status changed from Open to Closed I reviewed every recent RubyCI arm/aarch64 failure, and this test did not fail in any of them. So failures must be rare. I'm going to close this. If this is still an issue and someone can come up with a reproducible test case, that would be appreciated. ---------------------------------------- Bug #16920: TestThread#test_signal_at_join fails on aarch64 https://bugs.ruby-lang.org/issues/16920#change-104282 * Author: jaruga (Jun Aruga) * Status: Closed * Priority: Normal * Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN ---------------------------------------- I observed the following error on Ruby 2.7.1 building in Fedora aarch64 CI. It was just one time error. It does not always happen. ``` 1) Error: TestThread#test_signal_at_join: Timeout::Error: execution of assert_separately expired timeout (120 sec) pid 2314088 killed by SIGABRT (signal 6) (core dumped) | /builddir/build/BUILD/ruby-2.7.1/test/ruby/test_thread.rb:1346:in `test_signal_at_join' Finished tests in 1379.712832s, 15.2372 tests/s, 1972.9127 assertions/s. ``` -- https://bugs.ruby-lang.org/
