Is problem reproducible ?
=========================
  * yes 

How to reproduce (if reproducible):
===================================
  * From a program that use lttng API calls to create session, etc:
    :
    struct lttng_domain dom;
    :
    : //-- do not initialize dom.buf_type !
    :
    handle = lttng_create_handle(sessionName.c_str(), &dom);
    :
    // Then use lttng_channel_set_default_attr
    //          lttng_enable_channel
    //
