According to the error message, the load of the host function itself was
misaligned. From Bradley's email:
```
setup.c:2605:16: runtime error: load of misaligned address
0x000002a9f05f for type '___host' (aka 'long (*)(struct
___processor_state_struct *)'), which requires 8 byte alignment
0x000002a9f05f: note: pointer points here
ff ff ff ff ff 61 a4 4b 01 00 00 00 00 71 ed 4f f4 ff 7f 00 00 81 3f
4b 01 00 00 00 00 20 00 00
```
So the problem seems to be the cast `(___label_struct*)(pc-1)`.
