#47564 [NEW]: unpacking unsigned long 32bit bit endian returns wrong result

From: laacz at laacz dot lv Operating system: 6.1-STABLE FreeBSD (amd64) PHP version: 5.2.9 PHP Bug Type: Strings related Bug description: unpacking unsigned long 32bit bit endian returns wrong result Description: ------------ Unpacking unsigned long (32bit; always big endian; "N") on 64bit system returns 64bit signed int instead of 32bit. You can do & 0xffffffff on unpacked value, and get desired result, but that's still a bug. Reproduce code: --------------- <?php list(,$command_id) = unpack('N', chr(0x80) . chr(0x00) . chr(0x00) . chr(0x09)); echo hexdec(dechex($command_id)) . "\n0x" . dechex($command_id) . "\n"; ?> Expected result: ---------------- 2147483657 0x80000009 Actual result: -------------- 1.8446744071562E+19 0xffffffff80000009 -- Edit bug report at http://bugs.php.net/?id=47564&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=47564&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=47564&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=47564&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=47564&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=47564&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=47564&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=47564&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=47564&r=needscript Try newer version: http://bugs.php.net/fix.php?id=47564&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=47564&r=support Expected behavior: http://bugs.php.net/fix.php?id=47564&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=47564&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=47564&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=47564&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=47564&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=47564&r=dst IIS Stability: http://bugs.php.net/fix.php?id=47564&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=47564&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=47564&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=47564&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=47564&r=mysqlcfg
