Previous Comments: ------------------------------------------------------------------------ [2004-04-11 11:13:44] calum at lasham dot com expected result should be a backtrace ------------------------------------------------------------------------ [2004-04-11 11:11:08] calum at lasham dot com Description: ------------ When using the ++ operator on an overloaded object property that's not assigned a value, a debug_backtrace() in another unrelated object causes a crash. See example code to reproduce the problem. Note 1: The script executes correctly if, in the example code... $foo->bar++; is replaced with... $x = $foo->bar; $x++; $foo->bar = $x; Note 2: if the __set method in class Setter actually sets the variable on the object the script executes correctly. The bug appears in php5rc1 and the snapshot Built On: Apr 11, 2004 10:30 GMT. crash occurs when using php as apache module or from command line. Reproduce code: --------------- <?php class Setter { function __get($nm){ } function __set($nm, $val){ } } class Test { function backtrace(){ debug_backtrace(); } } $foo = new Setter(); $foo->bar++; $t = new Test(); $t->backtrace(); ?> Expected result: ---------------- "got exception" printed Actual result: -------------- apache service crash ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=27951&edit=1
