Preprocessed file

Effectively the problem can be showed with much less code lines. I just did a
custom iterator to show the problem (and removed my own array).

The problem comes from line 45. If the function takes a copy, it does not work
but if it takes a reference and do the copy inside (as shown line 52) it does
work.

Once again it works fine with Visual 2013.
