dmd 2.060

code:

template ReturnType(func...) if (func.length == 1) { }

struct BinaryOperatorX(string _op, rhs_t,C) {
    ReturnType!(mixin("C.opBinary!(_op,rhs_t)")) RET_T;
}

class MyClass {
    auto opBinary(string op, T)() { }
}

void PydMain() {
    BinaryOperatorX!("+", int, MyClass);
}

fireworks:
dmd: mtype.c:5254: virtual void TypeFunction::toDecoBuffer(OutBuffer*, int):
Assertion `next' failed.

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.

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.
