the class WitnessBuilder method getSCExecutionOrder.

    execEvents.addAll(task.getProgram().getCache().getEvents(FilterBasic.get(Tag.INIT)).stream().filter(executedCEvents).collect(Collectors.toList()));
    execEvents.addAll(task.getProgram().getEvents().stream().filter(executedCEvents).collect(Collectors.toList()));
    Map<Integer, List<Event>> map = new HashMap<>();
    for (Event e : execEvents) {
        // TODO improve this: these events correspond to return statements
        if (e instanceof MemEvent && ((MemEvent) e).getMemValue() instanceof BConst && !((BConst) ((MemEvent) e).getMemValue()).getValue()) {
            continue;
