Hello doko,

could you please tell if the work described in this issue is likely to happen in Bionic?

I'd like to use clang and with C++17 and with libstdc++-7-dev I'm running into the issue described in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=877838

There's an upstream libstdc++ work-around available in libstdc++-8-dev but I'm unsure if the -8 version is suitable for production due to only being available in 'universe' and having a kind of snapshot version.

Thanks,
Gregor
