ASan works on Windows, and it is used by Chrome and Firefox. Currently it

Basically you just pass -fsanitize=address to clang-cl compilations, but
linking is different.

You link against clang_rt.asan-i386.lib if you are building an executable

CRT, link against both clang_rt.asan_dynamic-i386.lib and
