Broken Timsort

[Josh via Digitalmars-d]

I've noticed that std.algorithm.sort uses Timsort for stable 
sorting, but as I don't know much about the implementation in D, 
someone more knowledgeable may be able to answer this. It appears 
that there is a bug in the Python and Java implementations of 
Timsort, and I was just wondering if this affects D?
