Comment(by kouji@…):

 I checked it with 2099c43a78f24f5108ba7205a4a1933c17202661 (Sun Apr 24
 21:43:50 2011 +0900). Then I got same warning messages.
 I report my reduction script below.
 {{{
 threads = []
 35.times do
   threads << Thread.new {
     GC.start

     raise NotImplementedError.new("Just kidding")
   }
 end

 threads.each do |t|
   begin
     t.join
   rescue NotImplementedError
   end
 end
 }}}

 And I report my command to run below.
 {{{
 $ i=0; while true; do ./miniruby issues/1288/reduction.rb; i=`expr $i +
 1`; echo $i; done
 1

 0x2000392a0, break on auto_refcount_underflow_error to debug.

 }}}

 Thanks.
