Leak when overwriting a bin. about aerospike-client-c

Here is the sanitizer output:

Ok I found the problem. Actually I assumed that the content of the list was somehow kept despite the actual struct being on the stack (the as_list could have been a pointer allocated upon as_arraylist_init), however this is not the case so the library was actually trying to destroy the valuep but it was not pointing anywhere valid.
