--- Comment #10 from Yves Vandriessche <yves.vandriessche at intel dot com> ---
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.

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.
