I think the reason why with -O2, it is exhausted, is because check and (I think fabs, might have 
already) gets inlined because unit-at-a-time is enabled on the 3.3-hammer branch (and the 
mainline also) at -O2 and above.
It would be nice to know if this bug is also on the mainline.
Also what happens if you add __attribute__((__no_inline__)) to the function check, does it still 
create wrong code?
