I was able to reproduce the bus error by grafting in ENOSPC conditions:

--8<---------------cut here---------------end--------------->8---

Note that, despite ENOSPC, the grafting derivation is marked as
succeeding.

After making some space, rebuilding the same derivation yields a
Conkeror that actually works.

The fix will be to error out upon ENOSPC.
