Bug #61764 [NEW]: output of unpack while 'I' used

From: Operating system: Linux PHP version: 5.3.10 Package: Unknown/Other Function Bug Type: Bug Bug description:output of unpack while 'I' used Description: ------------ php -r "print_r(unpack('I', pack('I', -30000))); gives 4294937296 on s390x but -30000 on x86_64. According to manual I think correct value should be 4294937296 on x86_64. Also perl returns this number for perl -e "print unpack('I', pack('I', -30000))" for these two architectures. Or have I misunderstood something? -- Edit bug report at https://bugs.php.net/bug.php?id=61764&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=61764&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=61764&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=61764&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=61764&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=61764&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=61764&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=61764&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=61764&r=needscript Try newer version: https://bugs.php.net/fix.php?id=61764&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=61764&r=support Expected behavior: https://bugs.php.net/fix.php?id=61764&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=61764&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=61764&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=61764&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=61764&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=61764&r=dst IIS Stability: https://bugs.php.net/fix.php?id=61764&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=61764&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=61764&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=61764&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=61764&r=mysqlcfg
