Since the assignment is causing a compiler warning, fix it by using memcpy instead. CC libvduse.o libvduse.c: In function ‘vring_set_avail_event’: libvduse.c:603:7: error: dereferencing type-punned pointer will break strict-aliasing rules [-Werror=strict-aliasin] 603 | *((uint16_t *)&vq->vring.used->ring[vq->vring.num]) = htole16(val); | ~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Suggested-by: Xie Yongji <xieyongji@bytedance.com> Suggested-by: Paolo Bonzini <pbonzini@redhat.com> Message-Id: <4a0fe2a6436464473119fdbf0bc4076b36fbb37f.1671741278.git.marcel@holtmann.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
