I agree. And no, I'm not aware of anyone having run into the issue on
4.6.x.

I actually tried backporting the above commit. It's not just a matter
of cherry picking, but it's trivial. I could not test the result,
though, because I can't build the tools from 4.6 with my gcc (6.3.0),
without backporting some toolstack patches too.

I can look into which ones are needed, but not right now. So I'm going
to put this on hold.

Thanks and Regards,
Dario
