[Vala] compiler segfault

[Luca Dionisi <luca dionisi gmail com>]

With this snippet of code:

using Gee;
void main()
{
    HashMap<int, int> x = new HashMap<int, int>();
    x[1]++;
    //  if we use   x[1] += 1;   would be ok
}

the compiler core dumps.
I am using 0.12
Is anybody willing to check if the bug is still there with newer versions?
