Comment 6 for bug 2000009

I think that nobody among the SBCL development has enough understanding of OBS to know how it would be harming the SBCL build; I think you're very much on your own.
(From my perspective, you lost me at "create an acount". I don't know what that means and I don't want to know)

One thing I can suggest is that you add something into handle_guard_page_triggered() in 'interrupt.c' to do:
 backtrace_from_context(context, 40000); // ridiculous number of frames, try showing them all
