>From what I can see, the `tp_clear` method of bufferedrwpair is called during >Py_Finalize() that leads to garbage collection. This NULLs `self->writer` for >the rwpair object. Later, in the same garbage collection routine, the `tp_clear` of textio (the wrapper) is called. This attempts to finalize its wrapped object by first calling the `closed` property of the wrapped object. This property read is propagated down to the wrapped bufferedrwpair, `bufferedrwpair_closed_get()`. At this point, `self->writer` for the bufferedrwpair object is already NULL from the previous clear. Hence, the crash happens because a NULL pointer dereferencing is attempted. ---------- nosy: +santa4nt _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue12340> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
