[Libevent-users] bufferevent_openssl_filter_new and event_base

Hello,

I am running into a problem where I am unable to properly free the event_base when using theÂbufferevent_openssl_filter.

I have a use case where I need to connect and immediately disconnect from a remote server.Â

This is the error I am seeing.

I attached a small test program demonstrating the problem. You will have to change the LIBEVENT_BASE_DIR variable in the included Makefile.

I am able to get around the problem by not freeing the underlying bufferevent or by using event_base_free_nofinalize but then we are leaking memory according to valgrind.

It is not clear to me that I am even setting up this stuff properly even though it is working well. Any insight would be greatly appreciated!

Thanks for your time!
