[VSDK] Crash with VDK_Cursor::ExecuteSQL

[Eric Forget]

Hi Ruslan,

The next line will crash.

cursor.ExecuteSQL("SELECT Table2.RecID FROM Table1, Table2");

If I replace with the next line it won¹t crash crash.

cursor.ExecuteSQL("SELECT Table2.RecID FROM Table2");

Originally I had something like: "SELECT DISTINCT Table2.RecID FROM Table1,
Table2 ORDER BY Table2.Name". I've just tried to reduce it for your
debugging.

Table2 is just 2 VDK_String:

    mName( "Name", 512 ),
    mLowerName( "LowerName", 512, NULL, fIndexed | fUnique )

Table1 has a lot of fields, with 1 VDK_ObjectPtr pointing to Table2.

At that point, the database has just been created. The diagnose says "All
right!"...

I didn't change a thing to the database structure. I just removed the
database to create a new one. It really looks like an uninitialized
variable...

Any idea?

Éric
