--- Comment #1 from Simen Kjaeraas <simen.kjaras at gmail.com> ---
By prodding the code a bit, I was able to get a compiler crash. I believe the
core issue is the same. Here's the simplified code:

struct S() {
    void fun() {
        gun("");
    }
    void gun(T)(T) {
        alias buggy = bug;
    }
}

alias X = S!();

void main() {
    X().gun(0);
}

alias bug =  __traits(getMember, X, "fun");

I've not been able to reduce it beyond this.
