--- Comment #11 from Francois-Xavier Coudert <fxcoudert at gcc dot gnu.org> --- (In reply to Iain Sandoe from comment #10) > The only small snag here is that llvm-symbolizer is not a 'standard tool' > but requires a devt build of llvm. I've filed a bug report with Apple, asking if they could provide llvm-symbolizer with the Xcode developer tools. We'll see if they consider it. In the longer term, we need to support Mach-O in libbacktrace. If I knew how to implement that, I would do it, but I simply have no idea. > AFAIK, sanitizer works fine on (x86) darwin "upstream" so we need to get to > the bottom of what we're doing/testing differently here. If one has llvm-symbolizer in PATH, and with PR63964 fixed, the sanitizer failures on darwin are down to: - testcases that need adjusting (patch submitted there: https://gcc.gnu.org/ml/gcc-patches/2014-11/msg02465.html) - c-c++-common/asan/strncpy-overflow-1.c: PR59148
