:rkraesig, since you are the author of the potential regressor, could you please take a look?

Comment 1

[Ray Kraesig [:rkraesig]]

5 winepulse.drv winepulse.drv@0xc45f

All crashes have winepulse.drv in their callstack, which implies that they're running on Wine... and indeed, the Wine implementation of ::RoGetAgileReference is just a stub. The Win7 implementation of AgileReference might be necessary on Wine.

[Bob Hood [:bhood]]

David, could you give us an idea of the Severity on this?

Comment 3

[David Parks [:handyman]]

I agree with Ray's comment 1. This is probably best reported to Wine -- maybe they can implement something similar to our prior GIT implementation, although it looks like they don't have any AgileReference support.
