If you create a function that uses
udf_compat!UC_div, then when it is called with parameters-2147483648and-1, it will crash due to overflow. The problem is that the upper bound of int is2147483647, so changing the sign causes a crash.n1andn2ininareint, so as a solution during the function call, you can cast them tolong long.
