I am not sure this code is supported. I think that currently the right way to use array ops is to give a wide enough as lvalue. But note this syntax can't be used (I have a bug report on this too) (the usage of [] has to become obligatory):

double[2] c[] = a[] - b[];

So you need to use something like:
double[2] c = void;
c[] = a[] - b[];
