I used a pre-released version of GCC 6 so it's possible something has
been fixed in the compiler in the meantime.

If you don't see the problem, go ahead and close this bug.
Unfortunately, I cannot do my own GCC 6 retests at the moment.

Finally new upstream version out and I got some time to package it.
Unfortunately I cant reproduce the problem not with 0.17.0-2 you
reported, nor with the new one.

I add gcc,cpp,g++ (>=4:6) to dependencies and run
sbuild --dist experimental --build-dep-resolver=aptitude

It installs gcc 4:6-20160101-3 but builds everything without problem:

Do I miss something?
