https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=225629 --- Comment #19 from Kenneth Salerno <kennethsalerno@yahoo.com> --- Created attachment 193898 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=193898&action=edit Patch to build lang/gcc6 with system clang When /usr/bin/cc is clang, lang/gcc5 segfaults trying to stage xgcc compiling itself. A workaround is to not build lang/gcc5 at all, which is only necessary for a system that /usr/bin/cc is gcc 4.2.1 and needs >= gcc 4.9 to build lang/gcc6 which cannot USE_GCC itself and therefore tries to bring in lang/gcc5...
