    Bug#18761: constant expression as UDF parameters not passed in as constant · 154c6e06
    unknown authored
    The code that set up data to be passed to user-defined functions was very
    old and analyzed the "Type" of the data that was passed into the UDF, when
    it really should analyze the "return_type", which is hard-coded for simple
    Items and works correctly for complex ones like functions.
