OK, the sqlite3 extension has a bug. It has code like:

    ---8<---
    void _pysqlite_final_callback(sqlite3_context* context)
    {
        PyObject* function_result;
        PyObject** aggregate_instance;
        int ok;

    #ifdef WITH_THREAD
        PyGILState_STATE threadstate;

        threadstate = PyGILState_Ensure();
    #endif

        aggregate_instance = (PyObject**)sqlite3_aggregate_context(context, sizeof(PyObject*));
        if (!*aggregate_instance) {
            goto error;
        }

        [......]

    error:
    #ifdef WITH_THREAD
        PyGILState_Release(threadstate);
    #endif
    }
    ---8<---

So, they are doing right to cleanup in case of error. But when threads
are not available, the function is like:

    ---8<---
    void _pysqlite_final_callback(sqlite3_context* context)
    {
        PyObject* function_result;
        PyObject** aggregate_instance;
        int ok;

        aggregate_instance = (PyObject**)sqlite3_aggregate_context(context, sizeof(PyObject*));
        if (!*aggregate_instance) {
            goto error;
        }

        [......]

    error:
    }
    ---8<---

And indeed, there's nothing after the 'error' label. And gcc does not
like that:
    connection.c:785:1: error: label@end of compound statement

So, the solution is relatively easy: add a dummy statement after the
label:

    error:
        ;
    }

And it works, now. I'll submit a patch soonish...

Regards,
Yann E. MORIN.
