    Problem Report Number 1527
    Submitter's Classification Test Suite problem
    State Resolved
    Resolution Test Suite Deficiency (TSD)
    Problem Resolution ID TSD.X.0809

    Product Standard Internationalised System Calls and Libraries Extended (UNIX 95)
    Certification Program The Open Brand certification program
    Test Suite VSU version 4.0.2
    Test Identification base/setregid 6
    Problem Summary TSD4U.00004 Test makes incorrected assumptions about saved gid semantics.
    Problem Text
    This test runs with the following definitions

    ugid = group id of user invoking test
    gid1 = VSU_NOT_INUSE_GID1
    gid2 = VSU_NOT_INUSE_GID2
    the sgid bit is set on sregid6_exc and the group id is set to ugid.

    But the test assumes that

    real gid = gid2
    effective gid = ugid
    saved gid = gid1

    when it is run.

    This is incorrect in that the saved gid is the saved of the effective
    gid *after* the file has been exec'd. In this case it would be

    real gid = gid2
    effective gid = ugid
    saved gid = ugid

    So the test fails.
