          Issue ID: 18905
           Summary: [Reg 2.079] C++ classes can no longer be used with
                    -betterC
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: regression
          Priority: P1
         Component: dmd
          Assignee: nobody at puremagic.com
          Reporter: bugzilla at digitalmars.com

Consider:

  extern (C++) class C { } // Error: TypeInfo cannot be used with -betterC

This worked with 2.074. TypeInfo with 2.074 was not generated for this class,
it just generated the vtbl[] which is fine.

Looks like 

https://github.com/dlang/dmd/pull/7799

is the culprit.
