Package: gcc-6 Version: 6.2.0-10 Severity: important gcc-6 as packaged is broken for normal use patterns when working on the mainline kernel. In particular, any git bisect session that strays into 4.8 and earlier requires rather unpleasant workarounds - either playing with kbuild variables in command line, or, equally unpleasant, patching Makefile on each bisection step and unpatching before moving to the next one.
This is *NOT* about debian kernel packaging; what had been broken is the use of gcc for mainline kernel development, which used to be a supported use case until October. And that definitely includes building the kernels resulting from git bisect. Unless you wish to argue that kernel work is not supported anymore, I don't see any way around Severity: important - "has a major effect on the usability of a package, without rendering it completely unusable to everyone".
