Description Mathias LANG 2020-03-02 18:40:21 UTC 
```
unittest {}
pragma(msg, typeof(__unittest_L1_C1));
```

Compile with `dmd test.d` and you get a segv. Compile with `dmd -unittest test.d` and it works just fine.
Tested with DMD v2.090.1 & madteer as of 2020-03-03.

What should typeof(__unittest_L1_C1) return, the actual function type or _error_?
