updated testcase
changed the test case to resemble my application a bit closer. Here it is
almost 40 times slower with -O3 than with -O0
The other strange thing with our app (that I can NOT recreate with a test case
so far) is that if I use -DUSE_OPTIMIZATION=1 in my app the -O3 compiled
version seems to go into an infinite loop.
