Cannot find -lasan using address sanitizer in MinGW in Windows (MinGW)

Question

I'm trying to use the gcc address sanitizer in Qt by adding CONFIG += sanitizer sanitize_address to my .pro file but I'm getting an error: cannot find -lasan.

How should I install the library?

I'm using the MinGW provided by Qt but I could also try a standalone version.

Unfortunately GCC does not support Asan on Windows: here's an excerpt from libsanitizer/configure.tgt:

case "${target}" in
  x86_64-*-linux* | i?86-*-linux*)
    ...
  powerpc*-*-linux*)
    ...
  sparc*-*-linux*)
    ...
  s390*-*-linux*)
    ...
  sparc*-*-solaris2.11*)
    ...
  arm*-*-linux*)
    ...
  mips*64*-*-linux*)

    ...
  aarch64*-*-linux*)
    ...
  x86_64-*-darwin[1]* | i?86-*-darwin[1]*)
    ...
  x86_64-*-solaris2.11* | i?86-*-solaris2.11*)
    ...
  *)
    UNSUPPORTED=1
    ;;
esac

Note that Clang supports it (with some effort - see wiki for details) and many people have successfully used it.
