If you can reproduce the stack overflow inside a debugger, it's got to be that you're hitting something that causes infinite recursion. The stack size in IE is large enough that you wouldn't exceed it through normal scripting, and you certainly wouldn't be able to encounter it by stepping through code in ordinary fashion in a debugger.
Is there any way you can make a reduced test case that I can play with? Have you reproduced this on more than one machine running IE8? In any event, 1.7.0.1 will make it so that we don't have to loop through and manually unregister event handlers on unload, so there's a light at the end of the tunnel. I'm not sure when I'll be able to release it, though.
