What embedded OS are you using? {Perhaps your INIT and SHUTDOWN
procedures/code is incorrect}.
If you are not using an embedded OS, why are you calling sqlite3_initialize and
sqlite3_shutdown? You do realize that the purpose of sqlite3_shutdown is to
indicate that you no longer require the use of the sqlite engine in the current
process because you are, well, finished with it?
