passing any value to that parameter which has the same size as the
    parameter (it basically acts as if there is an explicit type conversion
    to the parameter type around the value at the caller side). If a procvar
    has an univ parameter, all procvars whose corresponding parameter
    has the same size as that univ parameter are similarly compatible.

    This transparent compatibility can however cause crashes in case of
    of the procvars when one of the types is passed on the stack and the
    other isn't (because then the called routine will a) load the parameter
    from a wrong location and b) pop the wrong amount off of the stack at
    then end). Therefore FPC will warn in most cases where this can happen.
