DMD 2.059, OS X 10.6.8

Got a reduced test case for this:

template C() {
    alias void C;
}

class List(T, size_t N) {}

auto list(T...)() {
    return list_impl!(C!T);
}

List!(L, 0) list_impl(L)() {
    return null;
}

auto foldr(alias f, V, T, size_t N)(V, List!(T, N)) {}

auto map(alias f, T, size_t N)(List!(T, N)) {
    foldr!(a => f)(null, list);
}

void main() {
    auto l = list;
    map!(a => a)(l);
    map!(a => a)(l);
}

GDC fails with an internal compiler error but LDC 2.060 runs correctly and also seems to be corrected with DMD GIT 2.x UDA beta b

The problem that happens is that the frontend produces two copies of the same
map!(a => a)(l).

First being:  map!(__lambda4,void,0)
Second being: map!(__lambda6,void,0)

If the frontend were able to detect and correct this collision, the internal compiler errors (in gdc at least) would stop.

Regards,
Iain.

Seems to work fine with DMD 2.064 head.
