I can't debug the problem without information from a debugger.
But I can make a change to let you enter a specific slot to look at which might skip the problem?
Download v1.3. Run SlotsGrab and enter E at the prompt to only dump Slot E.
Install CodeWarrior Pro 4 and its MetroNub extension. Fix the cinttypes header as described in one of the source files. Build the SlotsGrab target. Debug the target from the IDE. Where does it stop? What error does it report?
