Two separate issues, both triggered by a recompilation activity while binding NAME accesses. The first was due to continuing to access the PIC structure after a lookup triggered recompilation activity, the second was due to not having any way to rejoin from a BINDNAME (there is no longer a need to distinguish this from other fallthrough opcodes, as the distinction was only needed for non-decomposed property incops).
