[Bug] unexpected error with continue

[ALPAC-4]

🐛 Bug

continue in while cause unexpected error. Here is the example codes

    fun a() {
        let index: u64 = 0;
        let sum = 0;
        while (index < 10) {

            if (index % 2 == 0) {
                sum = sum + index
            } else {
                index = index + 1;
                continue
            };

            index = index + 1;
        };
        std::debug::print(&sum);
    }

This causes the following error at index: In a loop, this typically means it was moved in the first iteration, and is not available by the second iteration.

I added copy to fix this, but _index is not updated.

    fun a() {

        let _index: u64 = 0;
        let sum = 0;
        while (_index < 10) {
            std::debug::print(&_index); // _index is not increasing when it get 1
            if (_index % 2 == 0) {
                sum = sum + _index
            } else {
                _index = copy _index + 1;
                continue
            };

            _index = _index + 1;
        };
        std::debug::print(&sum);
    }

Most weird part is when I add &index; before continue, it works as expected.

    fun a() {
        let index: u64 = 0;
        let sum = 0;
        while (index < 10) {

            if (index % 2 == 0) {
                sum = sum + index
            } else {
                index = index + 1;
                &index;
                continue
            };

            index = index + 1;
        };
        std::debug::print(&sum); // print 20 here
    }

I think that continue makes some error. Without continue, all the codes above works.
