I have no problem running a server with the newer gem, but the intensive Cucumber tests inevitably result in a segmentation fault. I can detect no pattern to where the crashes occur. I���m posting here (()). I���m hesitant because I read the (()) page and I don���t have reproducing code as required, since the segmentation faults happen in different places. Sometimes instead of a segmentation fault, the process just hangs indefinitely. I���ve gathered and attached logs from all combinations of the following: * OSes: MacOS X 10.8.2, Ubuntu 12.10 * Ruby 1.9.3: p194, p286, p327 * ibm_db gem: 2.5.9, 2.5.11 Looks like I can���t attach more than ten files at once, I���ll attach the MacOS logs separately. I also have Ubuntu core dumps if that helps, too big to attach. Here is a sampling of crashes under 1.9.3-p194 on MacOS X: /Users/username/.rvm/gems/ruby-1.9.3-p194/gems/activemodel-3.2.8/lib/active_model/attribute_methods.rb:431: [BUG] Segmentation fault /Users/username/.rvm/gems/ruby-1.9.3-p194/gems/activesupport-3.2.8/lib/active_support/callbacks.rb:414: [BUG] Segmentation fault /Users/username/.rvm/gems/ruby-1.9.3-p194/gems/activesupport-3.2.8/lib/active_support/core_ext/class/attribute.rb:98: [BUG] Segmentation fault /Users/username/.rvm/gems/ruby-1.9.3-p194/gems/cucumber-1.1.2/lib/cucumber/ast/step_invocation.rb:59cfp consistency error - send /Users/username/.rvm/gems/ruby-1.9.3-p194/gems/ibm_db-2.5.10/lib/active_record/connection_adapters/ibm_db_adapter.rb:1929: METHOD[BUG] /Users/username/.rvm/gems/ruby-1.9.3-p194/gems/ibm_db-2.5.10/lib/active_record/connection_adapters/ibm_db_adapter.rb:1929: [BUG] Segmentation fault /Users/username/.rvm/gems/ruby-1.9.3-p194/gems/json-1.7.5/lib/json/common.rb:155: [BUG] Segmentation fault /Users/username/.rvm/gems/ruby-1.9.3-p194/gems/sprockets-2.1.3/lib/sprockets/caching.rb:46: [BUG] Segmentation fault /Users/username/.rvm/gems/ruby-1.9.3-p194/gems/thin-1.3.1/lib/thin/headers.rb:27: [BUG] Segmentation fault /Users/username/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/securerandom.rb:140: [BUG] Segmentation fault /Users/username/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/time.rb:499: [BUG] object allocation during garbage collection phase /Users/username/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/webrick/httprequest.rb:174: [BUG] cfp consistency error - call0 /Users/username/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/webrick/httprequest.rb:399: [BUG] probable buffer overflow: 32 for 23 /Users/username/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/webrick/httpversion.rb:30: [BUG] object allocation during garbage collection phase /Users/username/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/webrick/log.rb:71: [BUG] Segmentation fault /Users/username/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/webrick/utils.rb:214: [BUG] Segmentation fault In case the above is inadequate, the outputs of (({ruby -v})) for each version on each OS: MacOS X: * (({ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-darwin12.2.1]})) * (({ruby 1.9.3p286 (2012-10-12 revision 37165) [x86_64-darwin12.2.1]})) * (({ruby 1.9.3p327 (2012-11-10 revision 37606) [x86_64-darwin12.2.1]})) Ubuntu: * (({ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux]})) * (({ruby 1.9.3p286 (2012-10-12 revision 37165) [x86_64-linux]})) * (({ruby 1.9.3p327 (2012-11-10 revision 37606) [x86_64-linux]})) Let me know if you need anything else! I���m definitely available to provide further logs and whatever is necessary to work through this. =end -- http://bugs.ruby-lang.org/
