Sorry, something went wrong.
When a SQL parameter sequence is an exact list, sqlite3 retrieved an element as a borrowed reference before taking ownership. On free-threaded builds another thread can replace it in between, so binding can use a freed object and crash. Fetch a strong reference atomically. Backport to 3.15 and 3.14.
