Subject: merge revision(s) 07b59eee6aa120537d7d72422327cc7b855e9400:

	[PATCH] Fix memory leak when load_from_binary raises

	ibf_load_code will leak memory allocated for the code if an exception is
	raised. The following script reproduces the leak:

	    bin = RubyVM::InstructionSequence.of(1.method(:abs)).to_binary

	    10.times do
	      100_000.times do
	        RubyVM::InstructionSequence.load_from_binary(bin)
	      rescue ArgumentError
	      end
	      puts `ps -o rss= -p #{$$}`
	    end
