I upgraded a rails application to rails 3.1 (rc4) and now get random segmentation faults in activesupport. These faults happen when starting the application (rails s) or running tests (e.g. rake spec). The weird thing is that:
- Sometimes all goes well and the segmentation fault does not happen
-
When the fault happens, it is always in activesupport, but not always in the same part
of it. See below for three different outputs: -
/home/corne/.rvm/gems/ruby-1.9.2-p180/gems/activesupport-3.1.0.rc /lib/active_support/core_ext/class/attribute.rb:66: [BUG] Segmentation fault
-/home/corne/.rvm/gems/ruby-1.9.2-p180/gems/activesupport-3.1.0.rc4/lib/active_support/core_ext/module/remove_method.rb:3: [BUG] Segmentation fault - /home/corne/.rvm/gems/ruby-1.9.2-p180/gems/activesupport-3.1.0.rc4/lib/active_support/core_ext/module/introspection.rb:79: [BUG] Segmentation fault
I’m not sure what the source of this problem is. Does anybody have an idea? Below is the full log for the first of the three shown above:
