Access violation in 13.9 under OpenGL

Since Catalyst 13.8 beta we've been getting many bug reports about crashes in Second Life on AMD GPUs using recent drivers.  I've spent a few days trying to track down the issue and I've come up empty -- all the usual methods of narrowing down the source of the problem have failed and the crashes don't seem to be related to anything in particular that the application is doing.  Rolling back to Catalyst 13.4 resolves the issue.


Is there a way to get more clarity on exactly where the driver is crashing?  


It's usually underneath a call to glDrawRangeElements, and always an access violation near NULL (eg " Access violation reading location 0x0000002c.")


The callstack is always deep in atioglxx.dll:
