Segmentation fault when using cloned unpacker

[rybakit]

Reproducer:

$unpacker = new \MessagePackUnpacker(true);
$unpacker = clone $unpacker; // <-- this line is causing the segmentation fault error
$unpacker->feed("\xc3");
$unpacker->execute();
$data = $unpacker->data();

@m6w6 Is there a reason why it can't be cloneable?

[m6w6]

It was just deemed too complex to copy the unpacker state to fix this issue, i.e. the crash.

You might want to create a feature request explicitly requesting clone functionality, so it won't get lost.

HTH,
