openmp task depend in c++ 15 compiler

Hi,

I'm experimenting with openmp task parallelism and the depend clause. The following code 

#include <iostream>

//void solve(int N, double* a, double* b) {            // this works
template<typename S> void solve(int N, S* a, S* b) {   // this does not
  int T = 4;
#pragma omp taskgroup
  {
    for (int i=0; i<N; i+=T) {
#pragma omp task depend(inout:b[i])
      {
        for (int k=0; k<T; k++)
          for (int l=0; l<k; l++)
            b[i+k] -= a[i+k+(i+l)*N]*b[i+l];
      }
      for (int j=i+T; j<N; j+=T)
#pragma omp task depend(in:b[i]) depend(inout:b[j])
        {
          for (int k=0; k<T; k++)
            for (int l=0; l<T; l++)
              b[j+k] -= a[j+k+(i+k)*N]*b[i+l];
        }
    }
  }
}

int main(int argc, char* argv[]) {
  int N = 64;
  double* a = new double[N*N];
  double* b = new double[N];
  for (int k=0; k<N; k++)
    for (int l=0; l<N; l++)
      a[k+l*N] = 1./((k-l)*(k-l)+1);
  for (int i=0; i<N; i++) b[i] = i;

  solve(N, a, b);

  for (int i=0; i<N; i++) std::cout << b[i] << std::endl;
}

fails with 

testDepend.cpp(9): error: invalid entity for this variable list in omp clause

  #pragma omp task depend(inout:b[i])

Is this not allowed? It works when I remove the template parameter, ie, just make it double and both versions work with g++ 4.9.1.

I'm using icpc (ICC) 15.0.0 20140530. It's a beta version. Sorry if this is already fixed in a later version of the compiler.
