--- Comment #28 from Ken Thomases ken@codeweavers.com --- Hmm. That's strange. The log doesn't show any of the WARN statements that my patch added. That suggests that the problem didn't occur and you wouldn't have had a crash even without my patch, at least on that run.
Was the crash completely reproducible every time? Is there any chance this was just a "lucky" run?
Basically, I'm looking for log lines which include "IOHIDDeviceGetValue". If there are no lines like that, then you wouldn't have crashed, anyway.
There's always a chance that the bug is due to something unrelated, like stack corruption. If that's the case, then just compiling a slightly altered version of the code could make it go away. :-/
