16:20:48dougk_there may be a silver lining to "no size function for object" bug that randomly occurs in threads.impure.lisp
16:21:30dougk_I think it happens when we're looking at a page with pinned code, but other objects were on the page before the pinned code, and those objects were evacuated from the page.
16:23:19dougk_basically gc_search_space can't step through the page because it has some forwarding pointers on it. https://sourceforge.net/p/sbcl/sbcl/ci/a33095b0 removed the ability to step over forwarding pointers
