Appears to only be an issue for the fidelity addresser. Temporal addresser still runs in about the same time as before the fidelity changes. ```lisp (let ((quil::*addresser-swap-search-type* :a*) (quil::*default-addresser-state-class* 'quil::temporal-addresser-state))...

Managed to scrounge it down to a smaller repro case. The following 13-line prefix of `benchmarking/quil-rewiring/0005q-0000160.quil` fails to compile in under 5 minutes. If I remove any one line from...

Slightly simpler example consisting of only `X`, `RX`, and `CZ`. This feels like a sufficiently simple case to just start poking it with a debugger. ``` X 0 X 1...

An extra tidbit. If I compile the above program of `X`/`RX`/`CZ` with a chip spec of `(build-nQ-linear-chip 20)`, then it does not terminate within ~12 hours. If I reduce the...

Shelving this for now to work on something else. Parting note to self. Here is a snippet from the logs when compiling the example [here](https://github.com/rigetti/quilc/issues/531#issuecomment-570726908) with a 20q linear chip:...

I was hoping that might be the case. Was planning to take a closer look and take his PR for test drive once the test failures there are resolved.

Was hoping the fix for #534 might coincidentally resolve this issue as well, but it seems not.

Maybe there is another "option 1.5" sort of halfway between (1) and (2) that mimics the existing QVM API by allowing the caller to specify a classical memory model at...

I'm warming up to the "declare once" model. It may have limitations, but at least it's simple and easy for the user to understand what went wrong and how to...
