In the mainloop function, calling __skynet_free__ frees the pointer which may has already been freed in __push_socket_data__.
mainloop(struct skynet_context * context, void * ud, int type, int session, uint32_t source, const void * msg, size_t sz) {
struct harbor * h = ud;
switch (type) {
case PTYPE_SOCKET: {
const struct skynet_socket_message * message = msg;
switch(message->type) {
case SKYNET_SOCKET_TYPE_DATA:
push_socket_data(h, message);
skynet_free(message->buffer);
// skip...
To fix this potential double-free bug, clear the pointer message->buffer in __push_socket_data__ after the pointer is freed.
