This query would invoke the following code in int4div:

if (arg2 == 0)
ereport(ERROR,
(errcode(ERRCODE_DIVISION_BY_ZERO),
errmsg("division by zero")));

result = arg1 / arg2;

I suggest directing some strong words to your compiler vendor. If the
"if" test doesn't complete before the subsequent division causes a trap,
that is not our problem.
