Hi, Sorry if I'm too far off the tree, but isn't this just an overlook of the dependency switch from libgcc1 (which has an "1" epoch) to the libgcc-s1 (which doesn't have an epoch)? ATM at least clang-9 (which is still the default in unstable) depends on libgcc-8-dev, and while I probably miss some important details, I fail to see why we have to drop gcc-8 because of this?
