Hi I confirm that for some benchmarks. However it is very hard to pin point the fault. The most probable thing is the incorrect implementation of some special instructions. For example, CFP benhcmarks uses some special instructions a lot. So if the instruction has not been implemented correctly, then the whole execution goes wrong.
