Bug #72584 [NEW]: Exception::__toString() fails after unserialize().

From: sb at vestergaardcompany dot com Operating system: Linux PHP version: Irrelevant Package: Class/Object related Bug Type: Bug Bug description:Exception::__toString() fails after unserialize(). Description: ------------ It seems that if an Exception object is serialized and unserialized, the resulting object does not have the private "previous" property set correctly. Invoking the __toString method on the resulting object generates a PHP Notice. Test script: --------------- <?php $e1 = new Exception("Test"); $e2 = unserialize( serialize( $e1 ) ); echo $e2->__toString() . "\n"; ?> Expected result: ---------------- exception 'Exception' with message 'Test' in /home/...php:2 Stack trace: #0 {main} Actual result: -------------- PHP Notice: Undefined property: Exception::$previous in /home/...php on line 4 PHP Stack trace: PHP 1. {main}() /home/...php:0 PHP 2. Exception->__toString() /home/...php:4 exception 'Exception' with message 'Test' in /home/...php:2 Stack trace: #0 {main} -- Edit bug report at https://bugs.php.net/bug.php?id=72584&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=72584&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=72584&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=72584&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=72584&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=72584&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=72584&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=72584&r=needscript Try newer version: https://bugs.php.net/fix.php?id=72584&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=72584&r=support Expected behavior: https://bugs.php.net/fix.php?id=72584&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=72584&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=72584&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=72584&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=72584&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=72584&r=dst IIS Stability: https://bugs.php.net/fix.php?id=72584&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=72584&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=72584&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=72584&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=72584&r=mysqlcfg
