SplFileInfo::getFilename() segfault in combination with GlobIterator and no directory separator

### Description

The following code:

```php
<?php
$contents = '英文看不懂咋办？';
file_put_contents('file1.txt', $contents);
foreach (new GlobIterator('file1.txt') as $fileInfo) {
	echo $fileInfo->getFilename();
}
```

Resulted in this output:
*segfault*

But I expected this output instead:
```
file1.txt
```
