QGIS crash when styling (with geometry generator)

Description

This feels a bit random and not with all layers.

When I try to build a complex style for a polygon layer including geometry generator and data defined overrides, QGIS tend to crash when applied to certain data.
It's not perfectly regular crashes, and it seems to depend on the layer. Sometimes QGIS freeze first, and sometimes it crashes immediately.

I've used, and crashed QGIS with Natural Earth 10M (https://www.naturalearthdata.com/http//www.naturalearthdata.com/download/10m/cultural/ne_10m_admin_0_countries.zip)

Symbol with two or more symbol layers.
top: Marker line, random size simple marker
middle: Geometry generator [buffer($geometry,-50)]
bottom: Simple fill

History

#1 Updated by Matthias Kuhn almost 6 years ago

Can you provide a complete project?

#2 Updated by Klas Karlsson almost 6 years ago

I tried to simplify a project as much as I could that generates a crash reliably on my computers:

When I apply the style from the "source_style" layer to the "crash_layer", QGIS will crash! Maybe not directly, but it will crash.

Zip file includes project and two layers in shape format. One has a style file attached.

The issue is probably layer dependent, since I have been able to create a simple shape file to apply the style to without QGIS crashing. But QGIS shouldn't crash regardless.

#3 Updated by Klas Karlsson almost 6 years ago

Also, just noted that QGIS don't crash until the "crash_layer" is visible in the canvas window. So if I apply the style when the layer is not in view it works fine, but as soon as I pan the layer into view, it crashes.

Same issue when the crash_layer is turned off. Apply style works fine, but as soon as layer is turned on, crash!

#4 Updated by Klas Karlsson over 5 years ago

More testing seems to indicate that the order of symbol layers matter.

In the "crash_test.zip" I change the order of the style layers of the "source_style" layer placing the Marker line in the middle. Then applying the style to the "crash_layer". This works fine, but when I change the order back so that the Marker line is on top, QGIS crash.

(note that I've saved the project I use in the video with the rearanged style layer order so I don't have to apply the style in the video.

Oh, and the debug output:

#6 Updated by Klas Karlsson over 5 years ago

Just tested on Windows 10 as well.

1. Add "crash_layer" from zip
2. create two style layers (marker line under, geometry generator over)
3. Change order of style layers
