Previous Comments: ------------------------------------------------------------------------ [2019-12-18 04:28:30] requinix@php.net Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If the script requires a database to demonstrate the issue, please make sure it creates all necessary tables, stored procedures etc. Please avoid embedding huge scripts into the report. Seems fine. https://3v4l.org/LhvkT Do you have any Zend extensions activated? Is there any difference if you enable or disable opcache? ------------------------------------------------------------------------ [2019-12-18 04:06:08] j124519951 at gmail dot com Description: ------------ When I run the test script in PHP 7.4.0, 100% run out of memory. Test script: --------------- <?php define('TEST_TEST', 1); class TestClass2 { function __construct() {} } class TestClass extends TestClass2 { var $test = [ TEST_TEST => 'test' ]; } new TestClass(); Actual result: -------------- Out of memory ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=78986&edit=1
