dict.items() set/list/tuple value segmentation fault & reverse items loop #322

I'm not entirely sure on Python 3 version differences so I'm not entirely sure if these are considered issues for PikaPython. But I'm creating this issue just in case if these are considered issues.

I tested this code and it results in segmentation fault. It does not matter if it's using (), {} or [], all of them seg fault.

dict = {
    'a': {1, 2, 3},
    'b': {4, 5, 6},
    'c': {7, 8, 9},
}

for k, (a, b, c) in dict.items():
    print(k, ':', a, b, c)

Another thing that was unexpected to me was this going through the dictionary in reverse.

dict = {
    'a': 1,
    'b': 4,
    'c': 7,
}

for k, a in dict.items():
    print(k, ':', a)

Output:

c : 7
b : 4
a : 1
