--- Comment #7 from Martin Liška <marxin at gcc dot gnu.org> --- So clang uses __sanitizer::LLVMSymbolizer: $ clang jhead.i -fsanitize=address -g && strace -f -s512 ./a.out 2>&1 | grep execv execve("./a.out", ["./a.out"], 0x7fffffffd520 /* 116 vars */) = 0 [pid 5529] execve("/usr/bin/llvm-symbolizer", ["/usr/bin/llvm-symbolizer", "--demangle", "--inlines", "--default-arch=x86_64"], 0x7fffffffd528 /* 116 vars */) = 0 which is probably not something we want to use.
