Comment(by simonmar):
You need to use a proper `SrcLoc` when calling `parseStmt`. e.g. the one
used by `GHC.runStmt` is `mkSrcLoc (fsLit "<interactive>") 1 1`.
The panic isn't a bug in this case, because the test code is invoking GHC
internals (`Lexer` and `Parser`). If you'd like us to expose more via the
GHC API, please make a feature request.
