Previous Comments: ------------------------------------------------------------------------ [2005-07-07 15:27:12] carlo dot razzeto at mtginfo dot com The same error is occuring when attempting to throw an exception from the deconstructor of a class while the script is shutting down. As my linux box is currnetly not available I tested on my windows workstation. I will verify this later today with my linux box.

Rather than generating a scripting engine error, PHP should allow for the script to deal with the error, for instance when an exception handler has been specified by the script. Reproduce code: --------------- class test { function __construct() { echo "Construct\n"; } function greet() { echo "Hello World\n"; } function __destruct() { echo "Destruct\n"; throw new Exception( 'test' ); } } $test = new test(); $test->greet(); Expected result: ---------------- Construct Hello World Destruct Fatal error: Uncaught exception 'Exception' with message 'test' in /home/crazzeto/test.php:13 Stack trace: #0 /home/crazzeto/test.php(13): test::__destruct() #1 /home/crazzeto/test.php(20): test::__destruct() #2 /home/crazzeto/test.php(20): unknown() #3 {main} thrown in /home/crazzeto/test.php on line 13 Actual result: -------------- [crazzeto@DEVEL crazzeto]$ php test.php Construct Hello World Destruct Fatal error: Exception thrown without a stack frame in Unknown on line 0 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=33598&edit=1
