[php-src] Issue #8167: PHP 8.1.3 *Iterator bug

Issue: https://github.com/php/php-src/issues/8167 Comment Author: Vermond125 Thanx for fast reply, @iluuu1994! My bad, I didn't provide full test, because it was coupled with framework and stuff, so here we go: The following code: ```php <?php $path = './Test'; $fileExtension = '.php'; $fileCount = 45; // Prepare the sandbox // Remove test sandbox if (is_dir($path)) { array_map('unlink', glob("$path/*.*")); if (!rmdir($path)) { throw new \RuntimeException(sprintf('Cannot recreate directory "%s"', $path)); } } // Create test sandbox if (!mkdir($path) && !is_dir($path)) { throw new \RuntimeException(sprintf('Directory "%s" was not created', $path)); } // Seed files inside test sandbox for ($i = 0; $i < $fileCount; $i++) { touch(sprintf('%s/%s%s', $path, sha1($i), // @note [!] I think it is hard for Iterator to swallow long names $fileExtension) ); } // Main part $iterator = new RegexIterator( new RecursiveIteratorIterator( new RecursiveDirectoryIterator($path, FilesystemIterator::SKIP_DOTS), RecursiveIteratorIterator::LEAVES_ONLY ), '/^.+' . preg_quote($fileExtension) . '$/i', RecursiveRegexIterator::GET_MATCH ); // @note This line is an actual bugfix // Add this line to get correct result // foreach ($iterator as $file) {} // Dummy loop to follow issue's case $i = 0; foreach ($iterator as $file) { $i++; } echo "$i files found\n"; ``` Resulted in this output: ``` 14 files found ``` But I expected this output instead: ``` 45 files found ```
