An escape with too many arguments overflows the stack, and a reference to an unsupplied argument copies arbitrary bytes into the query. The copy of a {d}, {t}, {ts}, or {escape} body also writes one byte past a 128-byte stack buffer. An application that forwards untrusted SQL text to the driver exposes its process to memory corruption.
