[Libevent-users]

[Ken Feng <kfmfe04@xxxxxxxxx>]

Hi,

I am a new user of libevent - I ran into the following valgrind error
on my machine:

Version: libevent-2.0.8-rc
OS: Ubuntu 10.04 LTS amd64

Of interest is (bufferevent_sock.c:321) inside:
struct bufferevent *bufferevent_socket_new()

struct bufferevent_private *bufev_p;
// ...
if ((bufev_p = mm_calloc(1, sizeof(struct bufferevent_private)))== NULL)
// ...
// ----------------------------------------

bufev_p doesn't seem to get freed with mm_free() unless there is an error.

My question is, what to do about this valgrind error?

1. There is no bug - suppress the valgrind message?
2. There is a flaw in the way I am calling bufferevent_socket_new().
In other words, I am not calling bufferevent_free() at the right time?
3. This code needs to be patched?
4. Something else?

Please advise.  Thank you.

- Ken
