#39301 [Bgs]: ip2long returns unsigned on x86_64 (buggy RETURN_LONG?)

ID: 39301 User updated by: fly2k at bk dot ru Reported By: fly2k at bk dot ru Status: Bogus Bug Type: Network related Operating System: N/A PHP Version: 5.1.6 New Comment: Can't agree... quote from http://php.net/ip2long: Because PHP's integer type is signed, and many IP addresses will result in negative integers, you need to use the "%u" formatter of sprintf() or printf() to get the string representation of the unsigned IP address. --- So, interger type is signed, results may be signed, and _IF_I_NEED_ unsigned, I will use %u or so... But what if I dont need and signed is ok for me? I want signed value but on x86_64 I gets unsigned... In any case, any function must return same result for same parameter at any platform, is not?

But on x86_64 returns 4294967294. Tried on two different hosts - one athlon64 with gentoo, other athlon64 with FC.
