[issue30347] itertools.groupby() can fail a C assert()

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

PR 1557 implements the simplest fix -- remove the assert and use Py_XSETREF() instead of simple assignment. Since the resulting code in _grouper_next() is identical to the code in groupby_next(), it was shared between these two functions.
