Another <no location info> error (Tuple section in pattern context)

Summary

For some syntax errors GHC cannot locate the error (: error: Tuple section in pattern context).

Steps to reproduce

ok               = (\ (0, _) -> (0, undefined))
-- But forgetting the underscore,
error_notLocated = (\ (0,  ) -> (0, undefined)) -- <no location info>: error: Tuple section in pattern context

Expected behavior

GHC should locate the error in the source code.

Environment
