Re: BUG #4190: sparc64 test suite fails

No, it failed. The code in question looks like this:

int64 arg1 = PG_GETARG_INT64(0);
int32 arg2 = PG_GETARG_INT32(1);
int64 result;

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

result = arg1 / arg2;

and the output you are showing indicates that the compiler thought it
could rearrange the code so that the division was executed *despite*
the protective test in front of it.

IMHO, what you have here is a compiler bug, or at least the gcc boys are
going to need to provide a damn good excuse why it's not.

BTW, kindly revert the patch you inserted in the Fedora repository.
