Checker RESOURCE_LEAK (subcategory none)
File: /src/mongoc/mongoc-cluster.c
Function _mongoc_cluster_add_node
/src/mongoc/mongoc-cluster.c, line: 1249
Assigning: "stream" = storage returned from "_mongoc_client_create_stream(cluster->client, &sd->host, error)".

       stream = _mongoc_client_create_stream(cluster->client, &sd->host, error);

/src/mongoc/mongoc-cluster.c, line: 1263
Resource "stream" is not freed or pointed-to in unimplemented function "mongoc_stream_failed".

          mongoc_stream_failed (stream);

/src/mongoc/mongoc-cluster.c, line: 1264
Variable "stream" going out of scope leaks the storage it points to.

          return NULL;
