import std.array;
import std.typecons;
struct T { }
struct S
{
RefCounted!T data;
}
void main()

Appender!(S[]) arr;
arr.put(S());
}

2.064:
$ dmd test.d
> C:\dmd-git\dmd2\windows\bin\..\..\src\phobos\std\array.d(2287): Error:
> variable std.array.Appender!(S[]).Appender.put!(S).put.item has scoped

However there is another bug in earlier releases:
2.063:
$ dmd test.d
$ test.exe
On win32 this crashes with a dialog box:
-----
[Window Title]
test.exe
[Main Instruction]
test.exe has stopped working
[Content]
A problem caused the program to stop working correctly. Please close the
program.
[Close the program] [Debug the program]

I've traced down the first version that crashes:
2.053:
> Crash
Earlier releases simply have an assertion failure:
2.052:
> [email protected](2351): Assertion failure
The code which failed there is:
-----
assert(RefCounted._store._count > 0);
