--- Comment #1 from [email protected] <[email protected]> --- Did this slip through because unit tests are run at compile time? Because the unit tests sure as hell should’ve caught this. I’d also recommend keeping template parameter order consistent between the versions of copysign(); it’s not a bug, but it could damned easily cause one if someone’s not paying attention. --
