Oh, Python 3.11 was aborted by an assertion failure on "s390x Fedora Clang 3.11" buildbot at commit 3b4f5ed:

    Oh, many tests failed!

    17 tests failed:
    test_audit test_bdb test_cprofile test_doctest test_import
    test_patma test_pdb test_profile test_pstats test_regrtest
    test_scope test_sys_setprofile test_sys_settrace test_threading
    test_trace test_unittest test_zipimport_support

    @pablogsal: I suggest to hold the next release until this issue is investigated!

    The assert breaks on big endian machiens because it is missing a _Py_OPCODE(). My PR #94411 removes the assert. It is not present in main.
