git clone https://github.com/danmar/cppcheck
git checkout 774a897
make CXX=path/to/clang-dev CXXFLAGS="-std=c++0x -fuse-ld=path/to/lld -flto=thin
-fsanitize=address" dmake


I can reproduce using llvm/clang built today and lld with assertions + asan +
ubsan.
I found this with a non-debug build of lld, it just segfaulted.
