Simple program breaks the compiler

[lurk101]

int main() {
    int a;
    a = 0;
    if (1) {
        int b;
        printf("%d\n", a);
        int c;
        b = 1;
        a += b;
        printf("%d\n", a);
    }
}

Results in

0
0
1

Clearly it should not print 3 numbers!

I will be happy to start working on this immediately, once pull request #96, "Improve robustness of ptr addition/subtraction", makes it through the review process.

Thank @HPCguy for the friendly reminder. I have applied #96.
