Some Brainfuck programs rely on the principle that once the data at current pointer reaches -128 and you try to decrease it, it will rollback to 127. The same thing applies when you try to increase the value that is 127. It should rollback to -128.
Example of such program is the current shortest Hello World program.
Currently the shortest Hello World program in Brainfuck:
+[>>>->-[>->----<<<]>>]>.---.>+..+++.>>.<.>>---.<<<.+++.------.<-.>>+.
If you try to run it, it will be stuck in cycle.
Possible solution is to change the type of "data" list from List to Uint8List
