Two such cases:
alexrp@alexrp ~/Projects/tests $ cat test.d
struct S
{
@disable this();
this(int x) {}
}
void main()
{
S f()
out (result)
{
}
body
{
return S(1);
}
}
alexrp@alexrp ~/Projects/tests $ dmd test.d
test.d(12): Error: variable test.main.f.result initializer required for type
const(S)
alexrp@alexrp ~/Projects/tests $ cat test2.d
struct S
{
@disable this();
this(int x) {}
}
interface I
{
S f();
}
class C
{
invariant()
{
}
S f()
{
return S(1);
}
}
void main()
{
}
alexrp@alexrp ~/Projects/tests $ dmd test2.d
test2.d(19): Error: variable test2.C.f.__result initializer required for type S
I bet more can be uncovered, but these are the only ones I've run into.
