    Problem Text
    For test case T.rcvudata 2, the VST4 test suite attempts to verify that
    a call to t_rcvudata() returns the associated related options specified
    on the corresponding call to t_sndudata(), after these have been subject
    to negotiation.

    This causes an execution loop in findoption() due to the fact that the return
    from t_rcvudata() is opt.len = 0 and the contents of the buffer pointed
    by opt.buf are not initialised.

    Under these conditions, which we believe to be conform to the Spec for
    t_rcvudata(), we cannot understand why the test suite is calling findoption()
    to analyse the contents of opt.buf . Only the test for a NULL pointer at
    the beginning of findoption() could avoid stepping through opt.buf, but
    our implementation does not set opt.buf to NULL. Stepping through non-
    initialised data could explain various strange behaviour, e.g. looping on
    a len=0 first element of an option or addressing outside legal address
    space (SIGSEGV) or by chance an "appropriate" len value to leave the while
    loop.

    Amending VST4 findoption.c to the latest version in VST5 avoids the loop
    and test case T.rcvudata 2 gives a pass result. However, it also induces a
    regression in the test case T.accept #6, due to a test suite defficiency
    in the VST4 accept.c routine getcurropt(), where results from t_optmgmt()
    are incompletely returned to the calling test case.


    We request that a TSD be accorded to authorise skipping the test case
    t_rcvudata #2 by replacing, in the tet_scen file, the line

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

    with the line

    /tset/XTI.os/clts/rcvudata/T.rcvudata{1,3-9}

    , there by building and executing the remaining 8 test cases.
    Test Output
    Looping in the VST4 findoption() routine for testcase t_rcvudata #2.
