Hi Marco,
I have had an error with similar behavior, I managed to bypass/fix it by declaring the inner (non-parallel) loops of my kernel as sequential using !$acc do seq.
Good luck!

The error does appear to have been found and fix in our internal development compiler and I have requested that this fix be add to our next release (10.2) due at the beginning of February. The work around to this issue is to use the flag "-ta=nvidia,oldcg".
Best Regards,

May I ask you what is "oldcg" for?

Hi Tuan,
"oldcg" is being used a work around for a bug in the "newcg". "cg" stands for code-generator. As of 10.0, we added new code generator targeting the NVIDIA GPU. Unfortunately, like may new features, there are bugs. In this case, the bug did not occur in the old code generator from the 9.0 release. Note that "oldcg" flag is not documented and will eventually go away.
