Hmm interesting, looks like it's this:
```
1 location added to breakpoint 1
```

That would happen on Linux when LLDB finds the breakpoint on `main` when the process is launched. Might be due to machine load/LLDB sluggishness that the output is printed later than expected. We can probably remove the check for `p ArrayRef`. Or not make it a `CHECK-NEXT`.
