Package: g++-6 Version: 6.3.0-6 Followup-For: Bug #854692 Dear Maintainer,
This looks a whole lot like https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79296 having now been backported into the gcc-6-branch, which would seem to warrant an escalation of the upstream bug. The "reduced testcase" attached there triggers the ICE now with 6.3.0-6, while it doesn't with 6.3.0-5. I can also confirm that pybind11 itself builds perfectly with testing's g++-6 6.3.0-5; this regression is new to 6.3.0-6. Having this regression migrate to testing would be a nuissance (upstream pybind11 itself uses debian testing for some of its travis-ci builds).
