RedisCluster::set is causing seg fault

Question

Getting seg fault as debugged using Gdb for the following snippet:

ConnectionOptions connection_options;
connection_options.host = "127.0.0.1";  // Required.
connection_options.port = 9001; // Optional. The default port is 6379.

ConnectionPoolOptions pool_options;
pool_options.size = 3;
RedisCluster cluster2(connection_options, pool_options);

cluster2.set("hello_key", "world_value");

The log from gdb:

Program received signal SIGSEGV, Segmentation fault.

The version of hiredis: 1.0.2.

The version of redis-plus-plus: 1.3.3

Compiled with C++ 11 option.

Am I doing any basic mistake ?
