restore(8) is unable to read back dumps created with both the
   previous and the current version of dump(8)...  What gives?

Why didn't you include the output from restore(8) to demonstrate what
it does?

I just tried it (again) on trinity, and it works fine for me.

I could imagine that it might fail if you built it with the old version
of dumprestore.h that redefined the DT_* symbols.
