    Test Identification Xt11/XtCvtStringToDisplay 1,2,3
    Problem Summary TSD4W.00149 These tests will fail if the DISPLAY environment variable is not set to the same value as the XT_DISPLAY configuration variable.
    Problem Text
    We believe this failure is due to a fault in the test suite, and request that
    a waiver be granted.

    It is not checking the XT_DISPLAY configuration variable. Notice in the
    sample code below that "*dispstr" is set to an empty string. Later "dispstr" is
    assigned to "fromVal.addr" which is passed to XtCvtStringToDisplay().
    The function XtCvtStringToDisplay() calls the function
    XOpenDisplay((char *)fromVal->addr). Since "fromVal->addr" is an empty
    string then XOpenDisplay() uses the "DISPLAY" environment variable. Unless the
    DISPLAY variable has been set the XOpenDisplay() function will fail causing the
    test to fail.

    A call to getenv("DISPLAY") just before XtCvtStringToDisplay() is called
    reveals that the DISPLAY variable has not been set.

    static void t001(){
    .
    .
    .
    /*
    * NOTICE THE DISPLAY STRING IS EMPTY. THE VALUE OF THE
    * CONFIGURATION VARIABLE "XT_DISPLAY" IS NOT USED.
    */
    char *dispstr = ""
    .
    .
    .
    fromVal.addr = dispstr;
    .
    .
    .
    /*
    * "XtCvtStringToDisplay()" CALLS "XOpenDisplay((char
    *)fromVal->addr)".
    * SINCE THE DISPLAY STRING IS EMPTY "XOpenDisplay()" LOOKS AT THE
    VALUE
    * OF THE "DISPLAY" ENVIRONMENT VARIABLE. UNLESS "DISPLAY" HAS
    * BEEN SET "XOpenDisplay()" WILL FAIL.
    */
    status = XtCvtStringToDisplay(display,
    &args[0],
    &num_args,
    &fromVal,
    &toVal,
    closure_ret);
    .
    .
    .
    }
