#44720 [NEW]: Encoding $_SESSION crashes with recusive arrays

From: antphill at uk dot ibm dot com Operating system: Linux PHP version: 5.2.6RC5 PHP Bug Type: Session related Bug description: Encoding $_SESSION crashes with recusive arrays Description: ------------ If I add create a global variable array which contains recursive entries it causes PHP to crash when I register it by calling session_register. This appears to be because the PS_ENCODE_LOOP macro does not check for recursion. Reproduce code: --------------- <?php $array = array(); $array["foo"] = NULL; $array["bar"] = NULL; $array["guff"] = NULL; $array["blah"] = &$array; var_dump(session_start()); var_dump(session_register($array)); echo "Done!\n"; ?> Expected result: ---------------- Perhaps we should check for recusion rather like the JSON extension does (see json_encode_array() in JSON.c)? Actual result: -------------- bool(true) -- Edit bug report at http://bugs.php.net/?id=44720&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=44720&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=44720&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=44720&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=44720&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=44720&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=44720&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=44720&r=needscript Try newer version: http://bugs.php.net/fix.php?id=44720&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=44720&r=support Expected behavior: http://bugs.php.net/fix.php?id=44720&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=44720&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=44720&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=44720&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=44720&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=44720&r=dst IIS Stability: http://bugs.php.net/fix.php?id=44720&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=44720&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=44720&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=44720&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=44720&r=mysqlcfg
