Edit report at https://bugs.php.net/bug.php?id=72594&edit=1 ID: 72594 Updated by: laruence@php.net Reported by: php+bug at tubul dot net Summary: Calling an earlier instance of an included anonymous class fatals -Status: Verified +Status: Closed Type: Bug Package: Reproducible crash Operating System: Linux, Windows PHP Version: 7.0.8 Block user comment: N Private report: N New Comment: Automatic comment on behalf of laruence@gmail.com Revision: http://git.php.net/?p=php-src.git;a=commit;h=8c5b27e0617bf0899d7e830ed3029711125a0ddb Log: Fixed bug #72594 (Calling an earlier instance of an included anonymous class fatals) Previous Comments: ------------------------------------------------------------------------ [2016-07-14 02:02:07] requinix@php.net Self-contained version: https://3v4l.org/H4q8L get_object_vars($oldFoo) shows nothing and get_class_methods($oldFoo) shows "bar". Calling $oldFoo->bar() fatals trying to allocate random amounts of memory. Doing new ReflectionMethod($oldFoo,"bar") crashes. Does not happen if $bar is defined after bing(). Moving to Reproducible Crash since it's possible to get one. ------------------------------------------------------------------------ [2016-07-14 01:17:00] php+bug at tubul dot net Description: ------------ 1) get an instance of an anonymous class returned from a included file 2) get another instance of the same class by including it again 3) have the second instance reference the first -> This gives a fatal error If in step 2) an exact copy of the file is included instead, the error doesn't happen. Leaving out the (never used) property of the class also prevents the error. PHP Version => 7.0.8 Configure Command => './configure' Server API => Command Line Interface Test script: --------------- <?php // test.php $oldFoo = require('foo.php'); $newFoo = require('foo.php'); // using a copy of foo.php here prevents the error $newFoo->bing($oldFoo); <?php // foo.php return new class{ public $bar; // comment out this line and there is no error public function bing($foo = null) { if ($foo) $foo->bing(); } }; Now run php test.php Expected result: ---------------- There should be no output Actual result: -------------- Fatal error: Uncaught Error: Call to undefined method class@anonymous::bing() in /home/richard/foo.php:6 Stack trace: #0 /home/richard/test.php(4): class@anonymous->bing(Object(class@anonymous)) #1 {main} thrown in /home/richard/foo.php on line 6 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=72594&edit=1
