V100.1: m_sceneView->screenToLocation causes crash

NorbertThoden — Tue, 21 Nov 2017 14:31:11 GMT

Hi!

Is Update 2 already "code freezed"?

It would be very nice if ESRI could take this problem into account:

I am able to reproduce a segmentation fault if a SceneGraphicsView is destroyed

(and screenToLocation where performed before).

Behaviour:
The basemap (crash should be reproducable using the topographic.tpk) is loaded and then:
- i resize the window and therefore the size of the scene widget ( i increase/decrease the width)
- move the scene using the mouse and release the button while moving
- destroy the scene (press 'create/destroy') while the scene is still moving
-> crash -> you got it -> verify call stack
-> create the scene again (press 'create/destroy')
start at the beginning

Based on my experience i need not more than 10 attempts to reproduce the crash.

EDIT:

Or you can simply use the second example "BasicSceneView_crashOnResizeDestroy_2017-11-21_automatic.tgz"
(Run and after several seconds....segFault)

I already opened an official case "Esri Case #02020238 - [BOS] segmentation fault on destruction",

and i will add the BUG number if available (hopefully only in a few days)

(I add the same example to reproduce the issue as attached to the case.)

Thanks in advance!

Hello Norbert!

We are very very close to code freeze, but we will take a close look at this one. Thank you for the thorough test cases.

Hi Eric!

Good to know, that the code freeze isn`t reached yet. So there is a chance that the bug can be solved 🙂

I don´t like to put more pressure than necessary but the truth is:

We need this bug to be solved or a 100%workaround until mid of February!

Almost certainly we have to escalate this bug otherwise.

Thanks for your support!

Norbert

Hi Norbert,

Using your test apps, I am trying the best I can to segfault....but no luck. This is Suse linux 64, yes? Which version of Qt? 5.9?

Hi Eric!

Linux:

ArcGIS: V100.1
OpenSuse 42.3 x86_64
Qt: 5.9.1
gcc: gcc version 4.8.5

The second example reproduces the problem in ~2 seconds

The first example requires manual interaction.

Here is the description:

I use the ESRI example 'BasicSceneView' to show a simple 3D scene.

I modified the user interface (ui) to create/destroy the sceneView clicking on a button.
(Use case: create an application and the use can switch between 2D and 3D.)

I add a timer calling m_sceneView->screenToLocation every 50ms.

Behaviour:
The basemap (crash should be reproducable using the topographic.tpk) is loaded and then:
- i resize the window and therefore the size of the scene widget ( i increase/decrease the width)
- move the scene using the mouse and release the button while moving
- destroy the scene (press 'create/destroy') while the scene is still moving
-> crash -> you got it -> verify call stack
-> create the scene again (press 'create/destroy')
start at the beginning

Based on my experience i need not more than 10 attempts to reproduce the crash.

Assumption:
The asynchron operation 'screenToLocation' is performed in a seperate thread (maybe more than one at the same time)
and there a not synchronized correctly while shutting down the scene/sceneView.

[Maybe the situation causing the problem is focused here!?
