Does the entire server really crash, or is just the process terminated.

As Greg said, the most likely reason is a bug in SQL Server. The other
alternative is a hardware problem (bad memory, bad disk sector).

If you open a case with Microsoft, they have a fix that addresses the
bug. But it's more likely that you will arrive at a working query by
tweaking in a bit, possibly using temp tables for intermediate storage.
