crash while using IDE inspector

[jaj@…]

I was inspecting a HEMLOCK-FRAME object, when I got a memory fault. I will try to see if it is reproducable.

I don't know if it's useful, but here is the output:

* Error in event process: Fault during read of memory address #x0

This is easily reproducible. In the listener do:

(inspect (car (ccl::windows)))

Then click on the frame in the left pane of the inspector, and scroll the middle frame down more than half way, and it crashes right away.

I think that this is fixed in changeset:7301
