Yes, but we first need to fix another issue, which is more important: several of the lang/gcc ports don't work properly, e.g. bootstrap stage comparison fails. There is also something fishy going on with gcc in base, which may or may not be related: building the devel/binutils ports with it causes cc1plus to segfault while compiling gold's archive.cc. I am still searching for the root cause; any help in this area would be greatly appreciated, as the maintainer has not responded yet. > Btw, is it possible to merge the patch into stable/10 as well? > It will make it possible to use clang35 there. Yes, this is also why I prefer to cherry-pick; I have set an MFC timeout of 3 days. -Dimitry
