This is interesting... MAP_ADD opcode is present in the code base

maybe you hit the yellow marked case...

Reproduced on Ubuntu 22.04 (python 3.10), with latest pycdc version:

$ cat t.py && python3 -m compileall t.py && pycdc __pycache__/t.cpython-310.pyc
d = {
    1: 1,
    2: 1,
    3: 1,
    4: 1,
    5: 1,
    6: 1,
    7: 1,
    8: 1,
    9: 1,
    10: 1,
    11: 1,
    12: 1,
    13: 1,
    14: 1,
    15: 1,
    16: 1,
}

The issue does not happen with less than 16 elements in the dictionary so I'm guessing some form of optimization for small dict is in play.

Might actually be a different issue. OP is mentioning python 3.9 and I can't reproduce on it.

Moreover, my issue look a lot like numba/numba#7894 which is python 3.10 related.

Should I open another issue?
