[Omp] Problems with optimisation

[Yuan Lin]

Have you tried -xopenmp=noopt?

If you think it is a compiler bug, we need to fix it. Do you mind
sending me (not the alias) the details of the problem, hopefully with
source code and makefile. It would be better if we can reproduce the
problem in house.

Thanks.

Is there any way to get around this problem? There is nothing unusual with the code, and it seems that it needs to run on a lower optimisation level. Thanks in advance.
