I hope this helps.

Thank you for an exellent program :-)

* What you were doing to get this message.

I was using the display window, where i had displayed a
pointer to (an array of) long int (allocated trhough calloc).

I displayed the first value of the array (*())

I selected that value (value was 0)

I pressed Plot History()

It crashed :-).

I just tried it again. It is reproducable.
