Reproducible Editor Crash - 4.6

Unity Engine
1

Hi there,

I’ve got a reproducible editor crash that’s preventing me from getting work done; the crash occurs when switching scenes (the initial scene last edited loads correctly, however loading any other scene, or hitting ‘New Scene’ will crash the editor with a Visual C++ Library error, “R6025 - Pure virtual function call”) - I have a open bug ticket for this as well (ticket #718287), project is not included as it is 54gb, however I am happy to run debuggers, et al if need be.

I am running on a slightly older editor build - 4.6.0f3; I have not upgraded as unfortunately we have another reproducible error on 4.6.1 onwards (specifically - prefabs wont save to disk, despite saving in the editor - a somewhat serious bug, which has been open for a while. [ticket #655942 incase anyone wants to look into that one - also quite reproducible!])

I suspect it’s related to a Gizmo script misbehaving; however there hasn’t been any changes to our scenes that we know about prior to this bug being triggered.

I have attached an editor log in the original ticket, however I have crashed unity over and over again while trying to debug this; the common thread is the stack traces seem to always be consistently the same; crashing occurring inside of Camera::PrepareSceneCullingParameters.

Received abort signal from the operating system

Interesting note; I tried loading a scene without the editor view active, and while it still crashed - the stack trace did change subtly. It’s still crashing in PrepareSceenCullingParameters, however - it’s doing so via a different path; which seems to rule out it being something gizmo/etc related.

Taking that a step further, I removed both Scene View & Game View tabs from my editor, and I was able to load another scene successfully. However, the moment I added the Scene view back, the editor instantly crashed again.

This bug appears to be fixed in 4.6.7 (or the act of installing the newer version fixed it - I did also suspect it could also be a vcredist issue), so this thread can b perhaps be closed. Issue #655942 involving prefabs not saving correctly also tentatively appears to be fixed as well (we last tested up to 4.6.5).
