Forcing a GPF

[Trax]

   Oh does this date! Many years ago I wrote a program which incorporated a Serial I/O library. As it turned out if you un-plugged and re-plugged the USB several times this Serial I/O library would generate a GPF (General Protection Fault). Since the GPF would not happen all the time I found some code posted here that when inserted in to a AutoIT program it would cause a GPF without fail. By GPF I mean the window "This program has caused an error and needs to close".

   Does anyone remember what code I can use to cause this type of GPF on purpose so I can debug? If it isn't called GPF any more what is it called?

Why on earth would you want to cause the GPF without an actual fail?

So I can write a recovery routine. Very hard to do if you can't get it to GPF with any consistency.

I'm not sure what you mean by GPF. Do you want the program to stop responding? If so do something like this:

GUICreate("", 700, 320)
GUISetState()
DllStructGetData(DllStructCreate("BYTE", 0x1), 1)
Exit
