SQLite is expecting you to return a SQLITE_ABORT on error and a 0 return code for no error. So you ought to wrap all your C++ callback in a try catch. Then in the catch return a SQLite SQLITE_ABORT error code, otherwise a zero.

Problems will occur if you bypass returning through SQLite as it will not free up/complete whatever code it does after you return back from your callback. This will cause untold problems potentially some of which maybe very obscure.
