Overflow in pow()

### Description

The following code:

```php
<?php
$a = gmp_init(10000000000);
var_dump(pow($a, $a)); // or var_dump($a**$a);
```

Resulted in this output:
```
gmp: overflow in mpz type
Aborted (core dumped)
```

But I expected this output instead:
```
float(INF)
```
