It looks like the issue is, if the invented CallExpr is ill-formed and the compiler needs to issue a diagnostic about it, with the invalid SourceLocation it doesn't have a source location to attach to the diagnostic.

I guess this means the approach of using an invalid SourceLocation doesn't work after all?
