Note your testcase has uninitialized variables, well the arrays are uninitizalized, after fixing them, it
gets worse:
subl $3532, %esp
Though on 4.0.0/4.1.0, we get better:
subl $260, %esp
which is funny but what ever.
3.3.3 by the way gives:
subl $636, %esp
3.4.0 gives:
subl $748, %esp
3.2.3:
subl $444, %esp
3.0.4:
subl $556, %esp
2.95.3:
subl $508,%esp
so 4.0.0/4.1.0 gices the best results.
