I can't invent a good name for this bug.
This looks valid CTFE code, but it doesn't compile:


int foo1(int n)(int[n] array) {
    foreach (el; array) {}
    return 0;
}
int foo2(int n)(int[n] array) {
    for (int i; i < n; i++) {
        int el = array[i];
    }
    return 0;
}
int spam() {
    int[1] array;
    enum int i1 = foo1(array);
    enum int i2 = foo2(array);
    return 0;
}
enum int r = spam();
void main() {}



Errors produced:
test.d(12): Error: cannot cast int to int[]
test.d(12): Error: cannot cast int to int[]
test.d(12): Error: cannot cast int to int[]
test.d(13): Error: cannot evaluate foo1(array) at compile time
test.d(13): Error: cannot evaluate foo1(array) at compile time
