--- Comment #10 from Yves Vandriessche ---
A similar internal compile error is triggered in find_rank when dealing with
two-dimensional array arguments, for both g++-5.2 and g++-6.1.1.
>void test(double Arr[][16]) {
> double A[16]= {0};
> for(int i=0; i<4; i++) {
>A[:] += Arr[i][:]; // internal compile error:
> // in find_rank, at c-family/array-notation-common.c:232
> }
> printf("%f \n", A[0]);
>}
This only happens on two-dimensional arrays. Passing a regular array (e.g.
Arr[16]) correctly yields a normal compile error (not an ICE); start-index and
length cannot be determined as `double Arr[16]` degenerates into `double *Arr`.
Complete test code has been attached attached.

reconfirming for g++ (Ubuntu 5.2.1-22ubuntu2) 5.2.1 20151010
compiling with -std-gnu++11 -fcilkplus
I did find a workaround: I do not get the error if I avoid using the array
notation extension on a member. Using a local variable that takes on the
pointer value of the member compiles perfectly.

I had the same error with the following code:
> class test{
> public:
> int arr[2][2][2];
>
> test()
> {
> arr[0:2][0:2][0:2] = 1;
> }
> };
>
>
> int main(){
> test t;
> return 1;
> }
And compiling with
> gcc cilk_test.cc -std-gnu++11 -fcilkplus
with gcc version:
> gcc (Debian 5.2.1-21) 5.2.1 20151003
The full output from the compiler was:
