[php-src] Issue #18867: error_reporting() Sometimes Sets Bizarre Values

Issue: https://github.com/php/php-src/issues/18867 Author: miqrogroove ### Description I'm having a strange problem with PHP 8.2.26 on a DreamHost server. I have a test case that gives a totally different result when I run it on the PHP sandbox at onlinephp.io, so I don't understand why this works in some environments but not others. When setting the error reporting level to -1 the server is interpreting that as a large negative integer. ``` <?php error_log('The default error reporting level is ' . error_reporting()); error_reporting(-1); // Report all errors error_log('Top of file error reporting level is ' . error_reporting()); error_log('The correct level would be ' . E_ALL); ``` Output: ``` The default error reporting level is 22517 Top of file error reporting level is -10251 The correct level would be 32767 ``` The reporting level is being set to -10251 which is not correct, and I'm not getting any error reports. Is there a bug here, or is this somehow specific to the server I'm using? ### PHP Version ```plain PHP 8.2.26 (cli) (built: Nov 21 2024 20:16:53) (NTS) Copyright (c) The PHP Group Zend Engine v4.2.26, Copyright (c) Zend Technologies with Zend OPcache v8.2.26, Copyright (c), by Zend Technologies ``` ### Operating System _No response_
