--- Comment #13 from Francois-Xavier Coudert <fxcoudert at gcc dot gnu.org> --- (In reply to Dominique d'Humieres from comment #12) > I guess it requires llvm-symbolizer in PATH. Where can I find it? Yes, that was the line above the one you quoted :) I got the latest LLVM here: http://llvm.org/releases/download.html#3.5 (Clang for Darwin 10.9) and put llvm-symbolizer in my PATH. With that, and with my patch under review (https://gcc.gnu.org/ml/gcc-patches/2014-11/msg02465.html), I am down to one failure: strncpy-overflow-1.c
