What does this mean?

Something like reported here:
digitalmars.D.bugs/3757

BTW, would you post the code sample that dmd 0.122 failed to compile?
Probably the circular interface inheritance bug was not fixed correctly.

Confirmed.  A circular inheritance detection bug was introduced in dmd 0.122.

Well, we still need a testcase for it!

The one you gave is one that indeed shouldn't compile.

Are you referring to the snippet below?
<code>
interface A:B{}
interface B:C{}
interface C:D{}
interface D{}
</code>

Why shouldn't it compile?

No.  I was referring to the one that you posted the URL to, of course.

I hadn't discovered the snippet above at the time.  That indeed should 
compile.
