Description Andrew Gvozdev

Looks like a peculiar one. I am getting some spikes in unusual CDT exceptions like bug 362574/bug 362464 and bug 304837.

Comment 1 Anton Leherbauer

Strange. That would mean the outline view input is set while creating the tree viewer. If that is possible, I would expect other unusual behavior as well.
How can I reproduce this?

Comment 2 Andrew Gvozdev

As far as behavior, maybe there was just a hint of paranormal activity. Some unexplained blinking maybe, difficult to pinpoint. The most annoying thing around that time was spontaneous expanding of "macro definitions" node in Outline view. I kept collapsing it but it kept expanding under my hands. It happened not in one particular editor but in any of them. I would click on a function in Outline view trying to select it and it caused "macro definitions" to expand and a different item to be selected.
I am not sure how to reproduce, seems to be one time thing. Maybe aftermath of Halloween.

Spooky.
I have committed a fix which makes it impossible to set the input before the viewer is fully configured.
