$ cat bla.d 
struct Foo {
    const x = Foo();

    static Foo opCall() {
        return Foo.init;
    }
}

$ dmd bla.d
::mangle(x)
dmd: mangle.c:81: char* mangle(Declaration*): Assertion `fd &&
fd->inferRetType' failed.
Aborted

Tested with dmd 1.061, where I removed the commented printf() in mangle.c line
37.

Probably related to bug 2080, since both involve type inference.

A partial fix:

https://github.com/D-Programming-Language/dmd/commit/1fc2fdb5fa9831eee2e1cae518ad350d517717c4

The error message is now:

test.d(2): Error: cannot implicitly convert expression (opCall()) of type Foo
to Foo

Compiles without error on D1 (1.072)

Give a forward reference error with D2 (2.058)

struct Foo {
    enum x = Foo();

    static Foo opCall() {
        return Foo.init;
    }
}

testx.d(5): Error: forward reference to type Foo
testx.d(5): Error: cannot implicitly convert expression (Foo()) of type Foo to
Foo
