I've just made the same test and it crashed too.
The problem is the driver falls in an infinite loop :
r600_context_flush -> r600_context_queries_resume -> r600_query_begin -> r600_context_flush -> ...
If you're using r600g driver too, maybe that's a hint there's a bug in how it handles queries/flushes (or it's simply a bug in my patch :-))
I'll have a look at this specific problem.
