Thanks for the quick update, Ralf! I've just added your changes to my app,
but for safety I wrapped the calls to
sqlite3_mutex_enter/sqlite3_mutex_leave in Try..Finally blocks.
I'll let you know if I run into any problems.
Best,
Nick

The modified code is in the attach. It is tested by a number of threads
which continuously create and destroy TDISQLite3Statements on a single
TDISQLite3Database instance for some time. Without the fix, the test caused
access violations at random times and places. With the fix, it passes
without problems.
I believe that the changes should work fine for you as well. Please keep us
posted on any issues.
Ralf
