(Not tested with the latest bug fixes, so this can be already fixed)


int foo() {
    int[] arr = new int[1];
    int s;
    foreach (x; arr)
        s += x;
    foreach (x; arr)
        s += x * x;
    return 0;
}
enum int _ = foo();
void main() {}


dmd 2.042 gives:

Error: Integer constant expression expected instead of null
test.d(10): Error: cannot evaluate foo() at compile time
test.d(10): Error: cannot evaluate foo() at compile time
