Description

I'm getting a segfault every few days inside an enumerator yield block:

    Enumerator.new  do |y| 
      cache.each do |k,v|      
        y << v if yield(v) #segfaulting here every million executions or so
      end
    end

Could you give us more small reproduce-able code?
I'm not sure it is core's matter or 3rd party issue.
