Expected behaviour

Clone should result in either an exception or an independent working object.

Actual behaviour

Using the cloned Redis object results in a segfault.

I'm seeing this behaviour on

• OS: Linux 5.6.13
• Redis: 6.0.1
• PHP: 7.4.5
• phpredis: 5.2.1

Steps to reproduce, backtrace or example script

$redis0 = new Redis();
$redis1 = clone $redis0;
$redis1->get('a');
Segmentation fault (core dumped)

It doesn't matter if you call ->connect().

I've checked

• There is no similar issue from other users
• Issue isn't fixed in develop branch => haven't checked sorry
