--- Comment #16 from Michael Matz <matz at gcc dot gnu.org> ---
At least the miscompilation of tree-vrp.c on x86-64 --enable-checking=release
bootstrap is due to the change in copy_prop_visit_phi_node().  The only
remaining one (in init_copy_prop) is harmless.

The dumps aren't that trivial to compare (many changes downstream the copyprop
passes), the diff of the disassembled tree-vrp is shorter, but also unwieldy.
So I hope Pat finds something from 176.gcc.
