#31894 [NEW]: Calling restore_error_handler inside destructor crashes PHP

From: adove at mindrage dot com Operating system: WinXP PHP version: 5.0.3 PHP Bug Type: Zend Engine 2 problem Bug description: Calling restore_error_handler inside destructor crashes PHP Description: ------------ This may be related to an older bug that was fixed (#24708) but I can reproduce reliably (having spent days and hours chasing!). Basically, if you call restore_error_handler from __destruct() things go horribly ary. Interestingly enough, calling restore_exception_handler works just fine. This happens both CLI and Apache 2.x. Note that it does not matter if you use $this or &$this in the constructor. Reproduce code: --------------- function __construct( &$aConfig ) { if(is_array($aConfig)) { $this->m_aConfig = &$aConfig; // Extraneous but it's in my constructor. set_error_handler(array &$this, "handleRuntimeException")); set_exception_handler(array($this, "handleException")); } } function __destruct() { //restore_error_handler(); restore_exception_handler(); unset($this->m_aConfig); } Expected result: ---------------- Proper ending of PHP script execution. Actual result: -------------- Segfault in php5ts.dll, ModVer: 5.0.3.3 Offset: 0004d661 -- Edit bug report at http://bugs.php.net/?id=31894&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=31894&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=31894&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=31894&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=31894&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=31894&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=31894&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=31894&r=needscript Try newer version: http://bugs.php.net/fix.php?id=31894&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=31894&r=support Expected behavior: http://bugs.php.net/fix.php?id=31894&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=31894&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=31894&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=31894&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=31894&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=31894&r=dst IIS Stability: http://bugs.php.net/fix.php?id=31894&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=31894&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=31894&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=31894&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=31894&r=mysqlcfg
