What does this program do, compiled with -std=c++11 -pthread ?

#include <mutex>
#include <system_error>
#include <assert.h>
#define VERIFY assert

int main()
{
  typedef std::mutex mutex_type;
  typedef std::unique_lock<mutex_type> lock_type;

  try
    {
      mutex_type m;
      lock_type lock(m);

      VERIFY( lock.owns_lock() );
      VERIFY( (bool)lock );
    }
  catch (const std::system_error& e)
    {
      VERIFY( false );
    }
  catch (...)
    {
      VERIFY( false );
    }

  return 0;
}
