It has no end command, and nothing was said what to do after the last line of the program is executed and no jump or end command is found - in that case you will violate the program borders and try to execute unexisted command. The test must be fixed (as well as test 2 and maybe some other tests, because the program without an end command is nonsense).

I managed to pass this test just by terminating the solution in case of program borders violation.

P.S. I hope no rejudge is scheduled, because my program is very slow and I know the test which can make it TLE easily ;)
