To do this, do 'make cleandir && make dependall DBG=-g' in
src/sbin/fsck_ffs on a different machine (so as not to touch the
broken volume) then run it.
Running it in gdb from single-user mode may not be feasible, in which
case the best approach may be to mount a ram disk, cd there, and let
it dump core, then copy the core file out.

That is probably true; one can easily get unfixable volumes from e.g.
mounting with -o async.
Oh, another important issue: was it running wapbl, softupdates, or
