Address Sanitizer Support

• Use Chromium's prebuilt Clang with sanitizer support.
• Sourced from WebKit's build instruction.
• Any others all doesn't work.

You can compile program with address sanitizer support using command like this:

clang cc -lc++ -std=c++11 -fsanitize=address main.cpp

You are liely to see this error:

dyld: Library not loaded: @executable_path/libclang_rt.asan_osx_dynamic.dylib
  Referenced from: /Users/Eonil/Workshop/Sandbox3/cpp-sanitizer-test/cpp-sanitizer-test/./a.out
  Reason: image not found
Trace/BPT trap: 5

This happens due to lack of runtime support library for address sanitizer. Copy these files from the Chromium's binaries into the executables folder.

libclang_rt.asan*_dynamic.dylib
