Hello,

Thanks for the report. We had one similar problem reported before:
http://software.intel.com/en-us/forums/showthread.php?t=75949

but we still couldnot reproduce this problem now. Isthis problem related to OpenMP setting?
if you set OMP_NUM_THREADS toother values, does the functionreturn othervalue?

Thanks,
Chao
