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.
