--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> --- I'd strongly prefer somebody interested in darwin to just add the libbacktrace support. And instead of obfuscating the testcase, either see why it is not symbolized by testsuite/lib/asan-dg.exp (asan_symbolize) either and fix that, or just disable asan.exp testing for darwin temporarily.
