------- Comment #4 from rguenth at gcc dot gnu dot org 2010-03-26 13:58 ------- 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.
