Patch working for us

Indeed, it seems to be a duplicate of the other bug.

We backported the GCC-7 patch and could build a working toolchain with it. The
original GCC-6 patch only added a warning but did not contain the actual fix
(for ABI compatibility reasons).

P.S. I'm attaching the patch we ended up with, in case anyone else can't easily
upgrade either.
