[app_server] crash in Desktop::Cursor()

[diver]

On real hw, while plaing around with SoundPlay, dunno how to reproduce yet.

Segment violation

Desktop::Cursor() Desktop::SetCursor() ServerApp::SetCurrentCursor() WindowsLayer::MouseMoved() MouseFilter::Filter() EventDispatcher::_EventLoop() EventDispatcher::_eventLooper()

This ticket is a little bit vague for a nomination as blocker of the alpha 1 release. Diver, can you try to find a consistent method for reproduction?

I didnt' sow this crash for year now. I think its fixed.

It hasn't been fixed yet, the code is still problematic. It only shows rarely, though (I remember running into it about two month ago the last time). Maybe it would be okay to move it to R1 instead, I dunno.

I didn't see it either for a _long_ time, but yesterday I got a crash in HWInterface::_DrawCursor(), which I believe is originating from the same problem. I should write a test app which constantly changes the cursor shape, I think this is what triggers it, together with something else in the cursor code.

Replying to axeld:

Let's keep it here until we are at a later stage in the alpha 1 process, and then reevaluate. Anyway, assigning to stippi because he should write a test app :-)

Hopefully fixed in r24741. The bug was/is very hard to reproduce, so I cannot verify that the problem I saw was the indeed cause. Please reopen if you encounter it again.
