Maybe you executed it in a thread and that died silently.  You can make 
the error explicit if you like:

$ irb
irb(main):001:0> t = Thread.new { raise "silent death" }
=> #<Thread:0x100106d4 dead>
irb(main):002:0> t.join
RuntimeError: silent death
         from (irb):1
         from (irb):2:in `join'
         from (irb):2
         from :0
irb(main):003:0> Thread.abort_on_exception = true

irb(main):004:0> t = Thread.new { raise "interpreter kill" }
