If you want some huge symbols, introduce Boost Lambda into a project. Doing a single for_each with a Boost Lambda can introduce symbols of several 100k.

Nice! I'm not near a C++ environment atm, but I promise an upvote to anyone who digs up one of these beasts for us to gawk at!

  Well, my memory was a bit wrong (it's been about 6 years since I last looked at this), and it's not as bad as I remember. It's not great, mind you, but here are the binary sizes for a simple program: Boost Lambda (unstripped): 44176 bytes Boost Lambda (stripped): 18808 bytes C++11 Lambda (unstripped): 24896 bytes C++11 Lambda (stripped): 14712 bytes Test program is pretty simple: #include <algorithm> #include <iostream> #include <vector> #include <boost/lambda/lambda.hpp> using namespace boost::lambda; int main(int, const char**) { std::vector<int> v; for (int i = 0; i < 100; ++i) v.push_back(i); //std::for_each(std::begin(v), std::end(v), std::cout << _1 << constant('\n')); std::for_each(std::begin(v), std::end(v), [](int i) { std::cout << i << '\n'; }); return 0; } I'm using Boost 1.58.0 and GCC 5.4.0 with -std=c++1y flag only to get the numbers above.
