That doesn't explain it, tho: the conservative stack scanning does check
to make sure the suspected pointer really does point to a real (tho
possibly dead) object, and we always know its type.

I.e. barring bugs in the conservative-scanning code, it should only
cause dead objects to be kept around (and scanned).  But those used to
be live, so they have been initialized.
