Issue #4289 has been updated by Eric Wong. File 0001-test-socket-test_unix-fix-test-failures-from-rb_mod_.patch added 0002-error.c-rb_mod_sys_fail-use-subclass-and-cache.patch breaks existing test cases that use assert_raise/assert_raises. This may be a dealbreaker for the patch, unfortunately... Actual code that uses "rescue Errno::EAGAIN" is unaffected. Anyways I have a patch to fix the failing test case I encountered if breaking existing Test::Unit code is alright... ---------------------------------------- Bug #4289: Timeouts in threads cause SEGV http://redmine.ruby-lang.org/issues/4289 Author: Motohiro KOSAKI Status: Assigned Priority: Normal Assignee: Akira Tanaka Category: core Target version: 1.9.3 ruby -v: ruby 1.9.3dev (2011-01-18 trunk 30591) [x86_64-linux] Derived from [Bug#4266] Running deadlock_test.rb in [Bug#4266] on trunk makes segfault. git bisect indicate first bad commit is below. --------------------------------------------------------------------------- commit d295957957c828588a8ca3c7b8619c7a93be6b5c Author: akr <akr / b2dd03c8-39d4-4d8f-98ff-823fe69b080e> Date: Tue Nov 2 22:37:08 2010 +0000 * vm_method.c (rb_clear_cache_by_class): just return if the class has no method. reported by Eric Wong.
