I hit this issue in msgpack-d with 2.061.

Following Tuple definition causes compilation error:

  Tuple!(ulong) a, b;  //  Tuple!(ulong) a; works

Error message:

  Assertion failed: (0), function syntaxCopy, file declaration.c, line 183.

A little minimized:


template Foo(T...) {
    alias T Foo;
}
struct Bar(U...) {
    template spam(U...) {
        alias Foo!(FieldSpec!(U[0])) spam;
    }
    alias spam!U baz;
}
int main() {
    Bar!(ulong) a, b;
}

This change introduces the regression.

https://github.com/D-Programming-Language/dmd/commit/dd79dd73f0a1553ff4237d759cea92e7222dccbb

But, I can't understand why the assertion is invoked...

Further reduced test case:

template Foo(T...) {
    T Foo;
}

struct Bar()
{
    alias Foo!int f;
}

void main() {
    Bar!() a, b;
}
