This query would invoke the following code in int4div:
   if (arg2 == 0)       ereport(ERROR,               (errcode(ERRCODE_DIVISION_BY_ZERO),
errmsg("divisionby 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.
