Libevent crashed on call to evhttp_request_free() about libevent HOT 4 CLOSED

Pretty sure the request should be freed automatically after the http_request_done has finished executing since you didn't use evhttp_request_own to take ownership of the request object so it results in a double free.

If you could paste a dump of the segfault information it may be helpful.

Thanks John for the quick reply. I would like to see "http_request_done" call back to free request object automatically. However, I see the TCP session is still there after the call back - which I wish to be closed.

John, you are right.

I used a debugger and found that even when I removed the call to "evhttp_request_free()", this function is still called.

But my test (wireshark sniffer) shows that the connection for the http request was not closed. Any idea how to close it? Thanks.

Better close this issue and open a new one. Thanks John.
