It was just some mess around code, but I'll avoid it in the 
future, so thanks for pointing it out :)

It does indeed look to be the same problem as 
http://d.puremagic.com/issues/show_bug.cgi?id=4414
I should also point out that the appearance of the error is 
dependant on the slice size.

How about this as a better test case?

ubyte[4] a;
auto x() {
    return a;
}
void main() {
    auto b = x()[1..$];
}
