Oh ok. I found a way to create a dictionary with equal keys and pass it to dict(**kw) in my fast_init branch (I already removed the PyUnicode_Check() asssertion in this branch): haypo@selma$ ./python bug.py call with: {'a': 1, 'b': 2} python: Objects/abstract.c:2471: _PyStack_AsDict: Assertion `PyDict_GetItem(kwdict, key) == NULL' failed. Aborted So yes, with special objects, the PyDict_GetItem()==NULL assertion fails. With pystack_asdict-2.patch, the duplicated (equal) keys are merged as expected: $ ./python bug.py call with: {'a': 1, 'b': 2} got: {'a': 2} Again, there is also a bug in my fast_init branch, I should avoid double conversion dict=>kwnames=>dict to call a type. ---------- Added file: http://bugs.python.org/file46408/bug.py _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue29360> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
