Error description

  • Configuration:
    --------------
    Tool = Rational Tau
    Version = 4.3.0.2

    ------------
    Having a variable, signal parameter etc of the type 'unsigned'
    char creates test values of '?'. Trying to remove these from the
    test values crashes Tau
    
    Work-Around:
    ----------------
    Remove all values instead of a value individually

    ****************************************************************
    The range of values for unsigned char is not suitable for
    printing as chars. The best example is the value 0 which
    makes Tau crash.
    

Problem conclusion

  • We have changed how unsigned char is read and written. It is
    now written as hex literals: 0x00 - 0xff. It can read hex or
    decimal values.
    

Temporary fix
