Bug potentially related to type inference and loops

[pdamme]

The following DaphneDSL script seems to make the DAPHNE compiler get stuck:

z = [0];
x = [1.0];
for(i in 1:2)
    z = z + x;
print(z);

When the first line is changed to z = [0.0]; it runs smoothly and prints the expected result:

DenseMatrix(1x1, double)
2
