You are kicking yourself and hurting everyone else by not updating.
With latest GCC, you should be able to do

Code:

std::vector<int> test;
std::for_each(test.begin(), test.end(), [&test](int size) { test.resize(size); });

Now compare that to what you are trying to do.

but do you know a 100% if i just can update gcc on an apple and use it with xcode ?

i would be extremely happy, because your code snippet looks so well ..

building GCC from source is no trivial matter, but it's not terribly difficult. I recently built 4.7 from the git repository on a couple of systems, and after installing a few extra necessary packages, it built without incident, and works great. I highly recommend upgrading to at least 4.5, if not 4.6 or 4.7. pre-built packages may even be available for mac.

thanks elkvis, i will give that a shot if i am having more time .. for now i just edited stl_vector.h .. quite dirty .. but the executable now builds and runs fine ..
