Mac OS: Leaks Sanitizer

Question

Mac OS X Sierra 10.13

I do as wrote here https://clang.llvm.org/docs/LeakSanitizer.html

I.e. created the small application with memory leak

#         


        

Answer 1

It seems that the Clang/LLVM shipped by Apple does not have -fsanitize=leak support. I fixed it by installing LLVM on Homebrew. A more detailed fix is on gist

$ brew install llvm@8

# Overwritten default Clang
$ echo 'export PATH="/usr/local/opt/llvm/bin:$PATH"' >> .zshrc

$ source ~/.zshrc
$ which clang
/usr/local/opt/llvm/bin/clang
