Using non-temporal (streaming) store Intrinsics get "Access violation" exception?

Hi,

I'm a newbie try to optimize my computational program. When I using streaming store Intrinsics replace regular store Intrinsics, I get the runtime error.

My application is a finite-difference program. This is the problematic codes.

_mm256_stream_pd( &A[idx], _mm256_add_pd( _mm256_mul_pd(C0, _mm256_load_pd(&A[idx])), _mm256_sub_pd(_mm256_mul_pd(C1, _mm256_sub_pd(Bz0, Bzy)), _mm256_mul_pd(C2, _mm256_sub_pd(By0, Byz)))));

Can't I use non-temporal Intrinsics in this case? I'm not very clear about the restrictions.

Thanks
