thanks for the bug report. I think this problem was not known so far,
and apparently Tobias has already opened a PR:

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54195

I remember committing some fixes for operators and generics some time
ago. Probably one of those is to blame. Will look into it soon ...

Cheers,
Janus
