Details on assambly

Using gcc -S file_name you can create assambly code alos available as gist. The assambly code comes out to be equal for both files as you'll see the int initialization can be seen different, and that is the only difference in the file with gcc --version which is gcc.exe (i686-win32-dwarf-rev1, Built by MinGW-W64 project) 7.2.0.

Graphs
