test.d:

ubyte delegate() outer() {
    ubyte inner() {
        return typeof(return).init;
    }

    return &inner;
}

class C {
    uint[] sortedIndices;

    void makeSortedIndices() {
        auto comparator = outer();
        bool greater(uint index1, uint index2) {
            return comparator() == 1;
        }
        sort!greater(sortedIndices);
    }
}

void sort(alias comp, T)(T data) {
    T less;
    size_t lessI = size_t.max, greaterI = data.length - 1;
    less[ti] = data[0..min(lessI, greaterI + 1)];

This is ice-on-invalid code. Reduced test case:

void bug6781(alias xxx)() {
    some_error;
}
struct C6781 {
    void makeSortedIndices() {
        int greater;
        bug6781!greater();
    }
}
