--- Comment #3 from Timur Iskhodzhanov <timurrrr at google.com> ---
Re c#2: if D virtuall inherits from B rather than C, the vftables match.

This is basically this is a dup of PR17738#c4 -- CL doesn't promote a vtordisp
thunk to vtordispex thunk when we have trivial non-virtual inheritance
somewhere in the middle of the hierarchy.

Closing this as WONTFIX as Clang does the right thing here.
I intentionally don't dup this against 17738 so we have a separate PR for this
specific CL bug.
