[php-src] Issue #14308: PHP 8.1.28 curl_exec crash with no error on first request after second request is made (fast F5)

Issue: https://github.com/php/php-src/issues/14308 Author: thundor ### Description The curl_exec crashes (maybe is aborted) on a first request after another (almost instantaneous) request has been done. The following code must be ran twice in the same browser window. SO: this script must be ran **TWICE** fast ```php $url = 'https://url-to-a-big-file'; $hash = md5(microtime(true)); register_shutdown_function(function() use ($hash){ file_put_contents(DIR_LOGS . 'testlock.log', $hash . ' - ' . __LINE__ . print_r(error_get_last(),true) . PHP_EOL, FILE_APPEND); }); // here i have some database checks, i'll just use sleep sleep(1); $ch = curl_init($url); file_put_contents(DIR_LOGS . 'testlock.log', ' - ' . $hash . ' ' . __LINE__ . PHP_EOL, FILE_APPEND); curl_setopt($ch, CURLOPT_TIMEOUT, 10); curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($ch, CURLOPT_FILE, $fp); file_put_contents(DIR_LOGS . 'testlock.log', ' - ' . $hash . ' ' . __LINE__ . PHP_EOL, FILE_APPEND); curl_exec($ch); file_put_contents(DIR_LOGS . 'testlock.log', ' - ' . $hash . ' ' . __LINE__ . PHP_EOL, FILE_APPEND); // NOT REACHED! No error <?php ``` Resulted in this output: ``` the DIR_LOGS . 'testlock.log' contains both $hash-es with no errors reported. The first hash does not contain the last file_put_contents. ``` But I expected this output instead: ``` The first request should have been completed successfully or the DIR_LOGS . 'testlock.log' should contain a fatal error of some kind. ``` ### PHP Version PHP 8.1.28 ### Operating System _No response_
