Wrapping a Pointer where auto_dealloc is True with another Pointer will cause double free.

[CookStar]

Code:

from memory import Pointer
from memory import alloc

def test_pointer():
 ptr = alloc(4)
 Pointer(ptr)

test_pointer()

Output:

free(): double free detected in tcache 2

This also applies to CustomType.

Code:

from memory import alloc
from memory import make_object
from memory.manager import CustomType
from memory.manager import TypeManager

manager = TypeManager()

class Test(CustomType, metaclass=manager):
 _size = 4

def test_customtype():
 ptr = alloc(4)
 make_object(Test, ptr)

test_customtype()

Output:

free(): double free detected in tcache 2
