Issue #9366 has been updated by hsbt (Hiroshi SHIBATA). Status changed from Assigned to Feedback @normalperson Do you still have this issue? ---------------------------------------- Bug #9366: "make -j32 check TESTS=-j32" occasionally fails on rubygems/specification https://bugs.ruby-lang.org/issues/9366#change-102267 * Author: normalperson (Eric Wong) * Status: Feedback * Priority: Normal * Assignee: hsbt (Hiroshi SHIBATA) * ruby -v: ruby 2.2.0dev (2014-01-05 trunk 44507) [x86_64-linux] * Backport: 2.3: UNKNOWN, 2.4: UNKNOWN, 2.5: UNKNOWN ---------------------------------------- This only happens occasionally, maybe 1 out of 10 times during "make check", so it's probably a bug somewhere with GC. I'll try to reproduce without parallel tests (could take a while). It seems to reproduce more easily on slower machine. I initially thought it was a bug in cachelined, but I can also reproduce it with plain trunk. /home/ew/ruby/lib/rubygems/specification.rb:748:in `block in _resort!': undefined method `name' for nil:NilClass (NoMethodError) /home/ew/ruby/lib/rubygems/specification.rb:747:in `sort!' /home/ew/ruby/lib/rubygems/specification.rb:747:in `_resort!' /home/ew/ruby/lib/rubygems/specification.rb:699:in `_all' /home/ew/ruby/lib/rubygems/specification.rb:882:in `each' /home/ew/ruby/lib/rubygems/dependency.rb:284:in `find_all' /home/ew/ruby/lib/rubygems/dependency.rb:284:in `to_specs' /home/ew/ruby/lib/rubygems/dependency.rb:309:in `to_spec' /home/ew/ruby/lib/rubygems/core_ext/kernel_gem.rb:53:in `gem' /home/ew/ruby/lib/rubygems/package_task.rb:25:in `<top (required)>' /home/ew/ruby/lib/rubygems/core_ext/kernel_require.rb:55:in `require' /home/ew/ruby/lib/rubygems/core_ext/kernel_require.rb:55:in `require' /home/ew/ruby/test/rubygems/test_gem_package_task.rb:3:in `<top (required)>' /home/ew/ruby/lib/rubygems/core_ext/kernel_require.rb:55:in `require' /home/ew/ruby/lib/rubygems/core_ext/kernel_require.rb:55:in `require' /home/ew/ruby/lib/test/unit/parallel.rb:114:in `run' /home/ew/ruby/lib/test/unit/parallel.rb:183:in `<main>' Some worker was crashed.
