This is an internal compiler error; it deserves some attention.

Also, confirmed that it still happens in latest git dmd.

Very marginally simplified. If you take out the "if (func.length == 1)" then it
segfaults instead.
-------------
template ReturnType(func...) if (func.length == 1) { }

struct MyClass {
    auto xopBinary(T)() { }
}

struct BinaryOperatorX() {
    ReturnType!(mixin("MyClass.xopBinary!(int)")) RET_T;
}

void PydMain() {
    BinaryOperatorX!();
}

Further reduced.
------------------
template T8602(func...) if (func.length == 1) { }

struct Bug8602 {
    auto xx() { }
}

T8602!(mixin("Bug8602.xx")) mm;

The problem is that at the end of CompileExp::semantic, the result is xx, but
the type of xx is still not known because it was a return-type inferred
function.

 struct Bug8602 {

The ICE is gone in git-head, now only gives:

Error: T8602!(xx) is used as a type

This is correct behavior, because T8602!(Bug8602.xx) does not make a type.

Maybe this is a dup of bug 5933.
