We've not heard that reported before, so I wonder whether there's not
something broken about your compiler or libc.

The code in question is in int2div() in utils/adt/int.c:

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

result = arg1 / arg2;

It's a bit hard to see how a compiler could get this wrong, but maybe
it's thinking it can evaluate the division before calling errfinish?
