19:17:24bikei don't understand the problem exactly, but if i change the scanner to use fields of ephemerons of weak pointers and ephemerons directly, the crash seems to go away
19:17:43bikeso mmtk needs an actual T_O**, not a shim, as i was putting in in order to fake weak pointers and ephemerons. i guess that makes sense
20:30:47drmeisterHow are things now? I didn't quite follow what you meant. Do you have to scan ephemerons?
