          Issue ID: 13150
           Summary: Add ability to log gagged compiler errors to file
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: DMD
          Assignee: nobody at puremagic.com
          Reporter: andrej.mitrovich at gmail.com

DMD does a lot of gagging and although ideally it would not have to do any
gagging at all, it's going to be a long time before this happens.

One problem with gagging is that it sometimes hides useful error messages
(sometimes even your own static assert with a custom message).

I propose we add an option to emit all gagged errors to a file. That way we can
at least attempt to trace through the compiler stages to see what went wrong.

This would require a new switch.
