[lldb-dev] EvaluateExpression has trailing error

[Greg Clayton via lldb-dev]

That doesn't seem to be right, you had a typename before:

(lldb) pp Ty
Fn(Void -> Int)*
= <unknown error>

Make sure everything is setup and is where you were stopped before and that you use the same "Ty" variable you did before. I have seen function types have newlines in them in the past.
