ID: 31569 User updated by: php at milonic dot com Reported By: php at milonic dot com Status: Open Bug Type: Math related Operating System: Fedora/Linux 9 PHP Version: 4.3.10 New Comment:
New test case at: http://www.milonic.com/bugreports/php_fc3.php Can also confirm that JavaScript will return the same values that older Redhat returns. This is getting weirder by the minute. Cheers Andy Previous Comments: ------------------------------------------------------------------------ [2005-01-16 15:38:38] php at milonic dot com UPDATE: Just to confirm that it's also the same with RPM-4.3.9 - so no matter if it's compiled from source or package. Also (was a long shot) changing precision in php.ini makes no difference either Cheers Andy ------------------------------------------------------------------------ [2005-01-16 15:19:48] php at milonic dot com Yes from source: gcc version 3.4.2 20041017 (Red Hat 3.4.2-6.fc3) one that I know works fine is: gcc version 3.2.2 20030222 (Red Hat Linux 3.2.2-5) Basically, all machines other than 'Fedora Core 3' are working fine. It's something in FC3 that is wrong, I just can't pinpoint it. It's a standard server install by the way, nothing special. Hardware also seems to be unrelated to the problem, tried it on 2 different FC3 servers and get the same result. Cheers Andy ------------------------------------------------------------------------ [2005-01-16 14:55:06] [EMAIL PROTECTED] Did you compile from source? If so, what are the different GCC versions on all machines? ------------------------------------------------------------------------ [2005-01-16 14:45:20] php at milonic dot com Narrowed the problem down to this: $b=251066875; $a=-3111919630; echo $b ^= ($a<<10); Fedora 3 echos: 251066875 (wrong) All other OS's echo: 25768443 (correct) Maybe it helps? Cheers Andy ------------------------------------------------------------------------ [2005-01-16 14:34:27] php at milonic dot com Sorry but it's still the same even with 4.3.11-DEV My guess is that this could be a Fedora problem but would like to know either way. It also seems unrelated to PHP version, happens on all of them both 4 and 5 - It all points to Fedora but just cannot think how. I'll dig a little deeper and let you know if I find anything Cheers Andy ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
