ODBC SQLSetPos Delete problem - Mailing list pgsql-odbc

Hi,

some weeks I have asked about a possible bug in pSQLODBC driver.

Now I have downloaded the driver source to get a debug version
of the driver.

The problem occurs at the following code line (973) in statement.c:

Code area:

mylog("type = %d and valuepointer here is %p\n", type, value);

if (self->manual_result)    {
    value = QR_get_value_manual(res, self->currTuple, lf);
    mylog("manual_result\n");
} else if (SC_is_fetchcursor(self))
    value = QR_get_value_backend(res, lf);
else {
    int    curt = GIdx2ResultIdx(self->currTuple, self, res);
    value = QR_get_value_backend_row(res, curt, lf);
}

mylog("value = '%s'\n", (value == NULL) ? "<NULL>" : value); // CRASH

The pointer value is 0xdddddddd

As for the log messages now I see , that I have forgotten a reload
after the deletion and the driver may not save this state to avoid
such a crash.

I do not know where the pointer comes from, but see this as a hint:

Could this be used for buffer overruns ?

Hope to hear from you :-)
