    Problem Text
    Above assertions would result in "Unresolved" because it set free
    for static allocated area by using t_free() in assertion #2.

    In assertion #2, it set static data area(optbuf,addrbuf) to
    opt.buf and addr.buf of structure t_unitdata.
    So, when it uses t_free() for structure t_unitdata, it will set
    free for static area, and those would be reallocatable.

    Subsequently, each process for creating structure t_unitdata after
    assertion #2 would be caught a SIGSEGV signal by controlling as
    reallocatable area.

    We think there will be a same problem in assetion #6.

    The behavier of t_free() is specified in the "XTI Library
    Functions and Parameters" section of the CAE Specification;
    it is as follows.

    "The function t_free() will check the addr, opt and
    udata fields of the given structure (as appropriate)
    and free the buffers pointed to by the buf field of
    the netbuf structure. If buf is a null pointer,
    t_free() will not attempt to free memory. After all
    buffers are freed, t_free() will free the memory
    associated with the structure pointed to by ptr."

    So we think it should set dynamic allocated area for t_alloc(),
    or should set NULL to opt.buf and addr.buf before calling t_free().

    /tset/XTI.os/clts/rcvudata/T.rcvudata 3 Unresolved

    Test Description:
    If the implementation supports a connectionless transport service,
    which supports the concept of a TSDU:
    When the number of bytes in the current TSDU is greater than
    unitdata->udata.maxlen, then a successful call to t_rcvudata( fd,
    unitdata, flags ) receives data into unitdata->udata.buf on the
    transport endpoint, sets T_MORE in flags, does not consume the
    T_DATA event associated with this data on the transport endpoint,
    returns the number of bytes received in unitdata->udata.len, and
    returns a value of (int)0. Subsequent calls to t_rcvudata()
    returns zero for the length of address and options until the full
    data unit has been received.

    If the implementation supports a connectionless transport service:

    t_errno to TBUFOVFLW, and sets the state of the endpoint as if the
