One case:

void main() {
    enum Foo { E }
    Foo f;
    switch (f) {
        case 1: break;
        default: break;
    }
}


dmd 2.047 prints:
test.d(5): Error: cannot implicitly convert expression (1) of type int to Foo
test.d(5): Error: case must be a string or an integral constant, not __error

Another testcase:

---
pragma (lib, l);
void main() {}
---

p.d(1): Error: undefined identifier l
p.d(1): Error: pragma lib string expected for library name, not '__error'

struct Foo {
    int x;
}
void main() {
    Foo(5 ^^ 5); // line 5
}

DMD 2.048 shows:
test.d(5): Error: must import std.math to use ^^ operator
test.d(5): Error: structliteral has no effect in expression (Foo((__error)))

---------------------------

void foo() {}
void main() {
    foreach (x; foo()[0 .. 1]) {}
}

DMD 2.048 shows:
test.d(3): Error: foo() cannot be sliced with []
test.d(3): Error: foreach: _error_ is not an aggregate type

struct Vec(int N) {
    int[N] data;
}
void main() {
    Vec!(1)([1, 2]);

Original D1 case is patched here: https://github.com/donc/dmd/commit/1acd2b64b10c4a985a10750d5ad83a0b7e98332b Other cases patched for D2: https://github.com/donc/dmd/commit/3a512771e31de4fb8b4e806154b08766fd97aed1 and for D1: https://github.com/donc/dmd/commit/327afade5bfe0551176ee17ab6c991139dcb8058

Another test case from bug 5288:

    if (z) return undefined;
    else return 0;
}
fixed here:
