Running the following code Mono (from CPython.ctypes.test_slicing) leads to all sorts of failures (upon exiting the program?):

from ctypes import *
import _ctypes_test
s = b"abcdefghijklmnopqrstuvwxyz"

dll = CDLL(_ctypes_test.__file__)
dll.my_strdup.restype = POINTER(c_char)
dll.my_free.restype = None
res = dll.my_strdup(s)
dll.my_free(res)

Does not occur consistently. Might be some sort of marshaling issue causing a double free?

The text was updated successfully, but these errors were encountered:
