 Clang version:

 {{{

/opt/local/bin/clang++-mp-3.3 --version
 clang version 3.3 (trunk 173279)
 Target: x86_64-apple-darwin12.3.0
 Thread model: posix
 }}}
Program:
 {{{
...
cat ./hello_world.cpp
 #include <cstdlib>
 #include <iostream>
int main(int argc, char* argv[]) {
     std::cout << "Hello, World!\n" << argc;
     return EXIT_SUCCESS;
 }
 }}}

 Trying to compile with memory sanitizer leads to linking errors:
