INADA Naoki added the comment: I think it's false positive of ASAN.
We have dynamically sized block. https://github.com/python/cpython/blob/3b0f620c1a2a21272a9e2aeca6ca1d1ac10f8162/Objects/dict-common.h#L49-L69 dictobject.c:547 calls memcpy to fill the block and head pointer is defined as `int8_t [8]`. ASAN doesn't know this is overallocated memory block. ---------- nosy: +inada.naoki _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue31166> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
