I would have done the latter as well, but I could only have channeled your analysis anyway. :) > Holler if you cannot reproduce the problem based on that. Likewise. I can create a GCC bugzilla account and add myself to the CC list if that helps. FWIW though, the fair.i file you attached is basically identical to what I'm getting, the only difference being a handful of file path strings. -- Earthling Michel Dänzer | http://www.amd.com Libre software enthusiast | Mesa and X developer -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
