[BUG-228011] Viewer 6.3.5 on Windows crashes silently - SL-11657

[sl-service-account]

What just happened?

Rez an object on the ground Go to edit, choose the contents tab Open inventory Locate any three scripts Drag these into the object Delete them in the object Repeat the drag from inventory

At either the moment the second drag is released or soon after the mouse pointer leaves the edit floater the viewer will exit silently. The crash may happen sooner in this sequence, but it'll happen at some point.

What were you doing when it happened?

Editing

What were you expecting to happen instead?

No crash :)

Other information

This may be a problem in llmousehandler.cpp - with Kokua 6.3.5 (where I first saw this) I get a log file entry about an Unhandled Enum within lLLMouseHandler::handleAnyMouseClick. I'll look into that more deeply later on today

The mouse aspect looks to be a false trail, this appears to be heading more into llviewerobject

Backing out the two commits associated with SL-11657 restores normal stability

I'm about to add a mp4 file showing the crash happening - the end of the movie is the crash point. Unfortunately the dump folder is empty so nothing to find from there

Reports that this is caused by the changes from SL-11657

Hello. Does this still happen? Please attach log files if you manage to repro, just in case.

I haven't tried to reproduce it since the initial report - I'll give it another try with the latest LL viewer and report back
