Description
**Describe the bug**
Running `hermit run -- ls` panics on an Intel 13900k (Raptor lake)
Indicate any of these common scenarios that apply:
- [ ] a program hangs under hermit
- [x] hermit panics internally
- [ ] hermit runs the program but divergence (nondeterminism) occurs
**To Reproduce**
`./target/debug/hermit run -- ls`
```
