Actually it fails to link. Both clang and gcc complain about missing
libasan symbols.

I find no providers of libasan in any of the gcc, llvm or clang packages.

It appears it is a submodule of both gcc and clang. So it likely just
need to be hooked up in the build for gcc.

Simple test case:

# echo 'int main() {return 0;}'|g++5 -Wall -fsanitize=address -o
/dev/null -x c -
/usr/local/bin/ld: cannot find -lasan
collect2: error: ld returned 1 exit status
