Type: Bug

1. remote ssh from MAC to Ubuntu
2. right click and select the "Create Implementaion" will reproduce it.

It can be reproduced by "Copy Implementaion" also.

[asynchronoust]

I also find this problem.

the following code for example:

class USocket 
{
public:
    USocket(int in_fd): socket_fd(in_fd) {}

    ~USocket()  
    {
        if (::close(socket_fd) < 0)
        {
            U_LOG("Socket Close Error fd: %d", socket_fd);   // this is the key of this problem
        }
    }

    void send(uint8_t* src, int32_t size);
    void recv();
    void listen(int backlog);
    void accept();
    void bind(const Address& addr);
};

when the ~USocket() implementation is written in header file，the "create implementation" for other funtions will cause 100% CPU, and the implementation of other funtions will not be created in cpp file , but when i create ~USocket() implementation in cpp file, the "create implementation" works well.

---

no no no, i finnaly the key point is the following code in ~UScoket() U_LOG("Socket Close Error fd: %d", socket_fd);

when i delete this line, even if ~USocket() implement in header file, it also works well. when this line exist, it does not work.

and U_LOG is the macro: #define U_LOG(Format, ...) fprintf(stdout, "%s:%d "#Format"\n", __FILE__, __LINE__, ##__VA_ARGS__); it is defined in other header file included in this .h file
