Compiled vs. interpreted ERT test

[Joost Kremers <joostkremers@fastmail.fm>]

Hi list,

I learned about the package `with-simulated-input`[1] which 
provides a macro of the same name that's intended for writing 
automated tests for code that takes user input. When trying to 
apply this in some ERT test, I found that it works fine if the 
tests are interpreted (e.g., loaded with `eval-defun`), but not 
when the test is byte-compiled. Byte-compiled tests fail with the 
following error:

```
(wrong-type-argument listp
                         #[nil "\300\207"
                               [t]
                               1])
```

I opened an issue on the package's Github page but the maintainer 
says he doesn't know how to debug this.[2] So I'm coming here in 
the hopes someone has an idea or a suggestion how to debug this.

TIA

Joost
