Comment 2 Guillaume 2015-12-02 23:07:36 UTC
As a side note, when it occurred I was using an entry in the watcher pane to set a variable value in my class with an expression like `m_MyInt = 1`
When I set it, the Continue option worked well to reach my next breakpoint then I used the step-over and... hung!
Comment 3 Guillaume 2015-12-02 23:30:24 UTC
Just got the exact same stack trace with breakpoints in the same region of code and without having the watcher assigning a variable value like previously... Stack trace is in VS2015 freeze 3.txt

Looks like killing the app on simulator is the workaround. It feels like old issues from Cycle 5...

Hi Guillaume,

Can you please confirm if you're still facing this issue with our current stable / beta builds?

I'm setting target milestone C9 in case this issue needs further investigation.

Hi Jose,

At the time I had the issue it was intermittent.
Now, I have not reproduced it in a long time since latest updates.

Oui can go ahead and close it. I will recreate a new one if I face any similar situation.

Changing status to not reproducible.
