I am no expoert on this, but I thought a bit about this problem.

My question is: is this on i386 or ppc and which optimization level -O0
versus -Os do you use. Can you try if this makes a difference?

Is the error always with test or is it mixed with test2 and direct
printf call calculation?

My feeling is that there maybe some problem with x87 fpu mode and float
-> int conversion.

Hope this helps, Christian
