Using the atttached code, I get a failure with the message on Darwin/arm64 and Linux/arm64. Per IRC, this cannot be reproduced on Windows/x8664 or Linux/x8664:
```
Unhandled SB-INT:SIMPLE-PROGRAM-ERROR in thread #<SB-THREAD:THREAD "main thread" RUNNING {7005DA0003}>:
invalid number of arguments: 3
```
I bisected this against sbcl and found that it started to break with commit 72b7caa and is currently breaking on master (4b98fdf).
