The test still passes, but you get a weird error about lldb-server crashing on
SIGHUP (another bug? see below). This also happens in the other test in that
file, but I didn't bother with it, I fixed it for the new test because it threw
me off when debugging it.
```
SIGHUP received, exiting lldb-server...
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and
include the crash backtrace.
