```php
<?php
$too_large = gmp_init("18446744073709551616");

var_dump(gmp_init(2) ** $too_large);
var_dump(gmp_init(2) << $too_large);
```
```
object(GMP)#3 (1) {
  ["num"]=>
  string(1) "1"
}
object(GMP)#2 (1) {
  ["num"]=>
  string(1) "2"
}
```
This is a follow-up of #21945 that we should reject large RHS gmp number objects.
