Is there a more detailed description of this problem in the mail archive?
Alas, I haven't been paying close enough attention, so a pointer would
be nice ;)...
As for the patch, I'm not really clear what is going on with the weakrefs
yet, but the portions that deal with gc'ing tramps and translated code
look fine. And, I think there is a small bug in the boehm-gc part of the
patch, you define an empty static version of KaffeGC_*WeakRef in gc2.c:
+KaffeGC_addWeakRef(Collector *collector UNUSED, void* mem UNUSED, void **ref UNUSED)
But there is also a real version in gc-refs.c, which might be ignored when
filling out the GC vtable. Or, maybe I'm just missing something...
