Search for "There are 4 forms of Unicode strings" in
Include/cpython/unicodeobject.h. char_size cannot be 0 in resize_compact():
it's checked by 2 assertions:
assert(PyUnicode_IS_READY(unicode));
assert(PyUnicode_IS_COMPACT(unicode));
The function cannot be called on a string which is not compact.
There is no bug, I close the issue.
Hopefully, Inada-san will remove state.compact field in Python 3.12 with his
PEP 623!
