Call that anything you like provided you're willing to stop disputing
reality:


    The internal SRI software exception was caused during execution
    of a data conversion from 64-bit floating point to 16-bit signed
    integer value. The floating point number which was converted had
    a value greater than what could be represented by a 16-bit
    signed integer. This resulted in an Operand Error. The data
    conversion instructions (in Ada code) were not protected from
    causing an Operand Error,
