Should bug reports be filed for discrepancies in the behavior of the threaded merge function in PHP?

The issue with the threaded merge function in PHP may be due to inconsistencies in how it handles merging arrays in a multithreaded environment. To solve this issue, you can implement a custom merge function that ensures thread-safe merging of arrays by using synchronization mechanisms like mutex locks. 

class ThreadedMerge {
    private $mergedArray = [];

    public function mergeArrays(array $arrays) {
        $mutex = new Mutex();

        foreach ($arrays as $array) {
            $mutex->synchronized(function ($mutex) use ($array) {
                $this->mergedArray = array_merge($this->mergedArray, $array);
            }, $mutex);
        }

        return $this->mergedArray;
    }
}

// Example usage
$threadedMerge = new ThreadedMerge();
$mergedArray = $threadedMerge->mergeArrays([ [1, 2, 3], [4, 5, 6] ]);
print_r($mergedArray);
