[Bug 1769657] Re: update toolchain packages for bionic

[Gregor Jasny]

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
