Segmentation fault

I'm stressing the rtmfp server by librtmfp. the main codes is:

int main(int argc,char * argv[]){   
    int flag = 1;

    snprintf(url, sizeof(url), "%s", url_flv + 6); // url_flv is a address of a rtmfp server. 

    RTMFP_Init(&config, &groupConfig, 1); 
    config.pOnSocketError = onSocketError;
    config.pOnStatusEvent = onStatusEvent;
    config.isBlocking = groupConfig.isBlocking = 1;
    RTMFP_InterruptSetCallback(IsInterrupted, NULL);    

    unsigned int context_keep = 0;
    unsigned int context = 0;
    context_keep = RTMFP_Connect(url, &config);    
    if (context_keep != 0) {
        try_again:
            context = RTMFP_Connect(url, &config);    
            if (context != 0) {
                RTMFP_Close(context);
                goto try_again;
            } else {
                RTMFP_Close(context_keep);
                RTMFP_Terminate(); 
                return -1; 
            }   
    }   
    RTMFP_Close(context_keep);

    RTMFP_Terminate(); // To ensure that invoker is dead
    printf("End of the Program!\n");

    return 0;

The running result is:

Hope you can reply

Hi,

Can you try with last version of librtmfp? Which version of MonaServer are you stressing? Can you send us your results? It could be interesting.

Thanks

Hi, I downloaded the latest version of the source code, but BUG still exists, the error information as follows:

I only use Static compilation， and use Main.cpp in "librtmfp-master/TestClient". I will send your Makefile and Main.cpp by Gmail. Thank you for your help.

Hi, The rtmfp server is: OpenRTMFP, not MonaServer.

[lxlenovostar]

Hi all. In the newest librtmfp, Segmentation fault is gone.
