This is very unlikely.  

I removed the #define statements and did:
{{{
[maik_at_horst tmp]$ g++  -O3 test.cpp -o test
[maik_at_horst tmp]$ time ./test

real    0m0.321s
user    0m0.273s
sys     0m0.003s
[maik_at_horst tmp]$ g++  -O3 -DNDEBUG test.cpp -o test
[maik_at_horst tmp]$ time ./test

real    0m0.045s
user    0m0.027s
sys     0m0.000s
}}}
