I think that there is at least one known issue with non-bootstrap builds (to do with flags not recognised by clang) but not sure, yet, if this is the same case. In general, if you want to build without boostrapping [as is often the case with development] then the best thing to do is to bootstrap a recent compiler [or the unmodified sources] and then use that GCC as your build compiler (this ensures you have compatible flags and builtins). thanks Iain
