gccgo: initialization cycle not detected #6684

The following program correctly reports an initialization cycle:

http://play.golang.org/p/xdFddyF8P0

Adding an interface type to line 7 (but leaving everything else unchanged) does not
report a cycle anymore:

http://play.golang.org/p/g61QvUmF2O

The spec is vague/incomplete with respect to cycles involving methods, but if a cycle
can be detected in the first case, it should be detectable in the 2nd case. The program
is self-contained and erroneous.

gc has the same bug (issue #6683).

Comment 1:

This is not a bug. It would require more work than what the spec is currently requiring
for detecting this case.
go/types also does not report this.

Status changed to WorkingAsIntended.
