Glibc detected error caused by memory leakage

A small mistake wastes me half a day ..

Sizeof (struct pointer) is not supported.

Although I understand this, I still make such an unforgivable mistake due to carelessness ..

The struct is defined as follows:

Typedef struct tagonlinenode

{
Int NID;
Int new_fd;
Struct sockaddr_in clientaddr; // online client host ADDR
Struct tagonlinenode * onlinenext;
P_mylistnode_t mynext;

}Onlinenode_t, * p_onlinenode_t;

 

As follow gets used to it, the head may be short-circuited instantly without thinking:

P_onlinenode_tOnlinenode = (P_onlinenode_t) Malloc (sizeof(P_onlinenode_t));

 

From then on.

Note: you cannot commit another crime!
