Hm, yeah - there's also PR41584 - another empty TU bug.

Usually this happens when we after writing out LTO IL drop some symbols because
we keep optimizing.  But we use the final set of symbols in the object files
for doing linker resolution - that's possibly a different state from what we
are going to read in during link-time optimization.

------- Comment #5 from rguenth at gcc dot gnu dot org  2010-03-26 13:58 -------
Which means that we should probably stop optimizing right after writing out
LTO IL and simply expand to RTL and assembly at that point.
