Description:

I get an unexpected error when running the attached script and passing it the file 'in' via `jruby c_jruby.rb < in` (expected output is "Case #1: 5\nCase #2: 6\n"):
c_jruby.rb:52:in `rise!': bad value for range (ArgumentError)
from c_jruby.rb:44:in `each_subrange'
from c_jruby.rb:50:in `rise!'
from c_jruby.rb:67:in `attacked!'
from c_jruby.rb:44:in `each_subrange'
from c_jruby.rb:64:in `attacked!'
from c_jruby.rb:143:in `(root)'
from org/jruby/RubyFixnum.java:285:in `times'
from c_jruby.rb:114:in `(root)'
Adding p() around "from...to" at line 52 actually prevents the error. And it seems pretty clear only integers are forming the Range, so this error should not be raised.
I could reproduce with a freshly compiled version on OS X as well as an old 1.7.0.preview2.dev on Linux.
I met a few ConcurrentModificationError before due to updating while iterating, but it should be fine now and I did not meet any since I added the "updates" Array line 49.
For info:
I was doing the Round 1C of Google CodeJam today, and searched for some kind of "interval map" and it turns out Java has a nice TreeMap which can be the base of that. The code tries to solve the third problem "The Great Wall"
