Bug report
The following code raises a SystemError.
import re re.match('((x)|y|z)*+', 'xyz')
Error message:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Users\Arttu\AppData\Local\Programs\Python\Python311\Lib\re\__init__.py", line 166, in match
return _compile(pattern, flags).match(string)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
SystemError: The span of capturing group is wrong, please report a bug for the re module.
((x)|y|z)++ gives the same error but (?>((x)|y|z)*) does not.
