Comment (by j...@…):
Two memory leaks if the socket is closed before closing the channel. Use
the ssh2.c example program (diff -u ssh2.c)

libssh2_channel_free(channel);
channel = NULL;
Memory leaked,
channel.c, line 160, '''session->open_channel'''
channel.c, line 170, '''session->open_channel->channel_type'''
Because the socket is now dead, any call to '''libssh2_channel_free'''
will return -7 "Unable to send EOF on channel" and fails before releasing
all the memory. You can't get beyond line 2293 and the call to
'''_libssh2_channel_close'''
I can find no line of code that sets '''session->socket_state''', which
would be useful.
