On today's mozilla-central I can no longer build with gcc-5. I get this error message: "internal compiler error: in make_ssa_name_fn, at tree-ssanames.c:151" This was with gcc 5 (Ubuntu 5.4.0-6ubuntu1~16.04.4) 5.4.0 20160609.
Downgrading to gcc-4.9 like our automation uses seems to fix the issue for me.
You should file an Ubuntu bug against gcc-5.
