Possible crash if SQLiteConnection.dispose() is called from a different thread #18

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago

Access violation/segmentation fault is possible in the following scenario:

1. T1: open connection
2. T1: start any method that use sqlite3* handle
3. T1: method checks handle/state for validity, releases lock
4. T2: dispose is called, handle is now invalid
5. T1: method uses now-invalid handle - crash

The behavior is not specified. It could linger. The library may take best 
effort to shut it down.
