Heap buffer overflow while opening a database.

[mannol]

No previous data-base file is present. This happens when I use user.db (or anything less than 9 characters) as an input for rliteConnect()

Relevant line (filename length is not checked I suppose):
if (memcmp(filename, ":memory:", 9) == 0) {

ASAN output:
