On builds using CPython's fallback getaddrinfo(), an allocation failure while constructing address results can return success with a null result, and the canonical-name path can ignore a helper error. socket.getaddrinfo() can then return an empty list, other callers can crash when they dereference the null result, and partially built address lists may leak. Set EAI_MEMORY, propagate helper errors, and keep the partial list available for cleanup.
(cherry picked from commit 7c39e8f)
