Yes. It turns on both the sanitizers. But I am not able to enable only ubsan in the latest xcode 8.2 version. When I enable only ubsan, I get the following linker error: ld: file not found: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../lib/clang/8.0.0/lib/darwin/libclang_rt.ubsan_osx_dynamic.dylib - Yegappan -- -- You received this message from the "vim_dev" maillist.
