# Arrays and scalars cannot be mixed

This is because the preprocessor does not realise that the local array takes precedence over the scalar.

int main() {
init_grid (64);
scalar s[], p[];
foreach()
s[] = p[] = 1.;
foreach() {
variable ‘p’ set but not used [-Wunused-but-set-variable]
    double p[3]; // renaming p to something else fixes the problem
for (int i = 0; i < 2; i++)
p[i] = s[];
}
}
