Hi all, serinus has been complaining about the new gcd functions in 13~: https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=serinus&dt=2021-06-03%2003%3A44%3A14
The overflow detection is going wrong the way up and down, like here: SELECT gcd((-9223372036854775808)::int8, (-9223372036854775808)::int8); -- overflow -ERROR: bigint out of range + gcd +---------------------- + -9223372036854775808 +(1 row) That seems like a compiler bug to me as this host uses recent GCC snapshots, and I cannot see a problem in GCC 10.2 on my own dev box. But perhaps I am missing something? Thanks, -- Michael
